Integrates five open PRs in one branch so they are built, tested and played together, with one CI run. Each PR keeps its own commits; one conflict in launcher-rust/src/core/i18n.rs (#1276 and the cheat texts on main) was resolved by keeping both sides. One fix found while playing the branch is added on top.
Fixed a stale SnormNz texture descriptor with data format 15 stopping the game in Oly400 (MapNumberConversion)
Validation:
Built on Windows (MSYS2 CLANG64) and passed the 8 GPU tests, including the new reg-dirty-test and frame-pacing-test
Built on Linux (Ubuntu 24.04, WSL) and passed build.sh --test
Passed surface-format-test with the new SnormNz cases; it aborted without the fix
Passed 860 of 863 launcher tests; the 3 save_backup restore tests refuse to run while the game is open on the test PC and touch no changed code
Failed savedata-test on Windows at test_savedata.c:57, the same as on main
Played on Windows 11 with an AMD RX 6700 XT, CUSA01623, 2560x1440: XeSS, FSR 4, TAA and graphics changes checked in game; a long FSR 4 session (296 area loads through Poseidon, Hades, Olympia and the Basilica, including Oly400) ended with no fault and a normal exit
Saw one crash on a load with FSR 4 whose log was overwritten when the game started again, so its cause is unknown; it did not happen again
Not tested on Polaris, Intel Arc, Linux NVIDIA 595 or macOS
Integra cinco PRs abertos numa branch só, para compilar, testar e jogar todos juntos, com uma rodada de CI. Cada PR mantém seus commits; um conflito em launcher-rust/src/core/i18n.rs (#1276 e os textos de cheats da main) foi resolvido mantendo os dois lados. Uma correção encontrada jogando a branch entra por cima.
Corrigido um descritor de textura obsoleto com SnormNz e formato de dados 15 que encerrava o jogo em Oly400 (MapNumberConversion)
Validação:
Compilado no Windows (MSYS2 CLANG64) e aprovados os 8 testes de GPU, incluindo os novos reg-dirty-test e frame-pacing-test
Compilado no Linux (Ubuntu 24.04, WSL) e aprovado o build.sh --test
Aprovado o surface-format-test com os novos casos de SnormNz; ele abortava sem a correção
Aprovados 860 de 863 testes do launcher; os 3 testes de restauração do save_backup se recusam a rodar com o jogo aberto no PC de teste e não tocam código alterado
Reprovado o savedata-test no Windows em test_savedata.c:57, igual na main
Jogado no Windows 11 com uma AMD RX 6700 XT, CUSA01623, 2560x1440: XeSS, FSR 4, TAA e mudanças gráficas conferidos no jogo; uma sessão longa com FSR 4 (296 carregamentos de área por Poseidon, Hades, Olímpia e a Basílica, incluindo Oly400) terminou sem falha e com saída normal
Visto um crash num carregamento com FSR 4 cujo log foi sobrescrito ao abrir o jogo de novo, então a causa é desconhecida; ele não se repetiu
Não testado em Polaris, Intel Arc, Linux com NVIDIA 595 nem macOS
Joined guest threads now free their Linux stack mapping and TLS block in thread_join, instead of retaining them for the session. Detached guest threads stay joinable at host level and a reaper thread joins and reclaims them on exit, since a thread cannot unmap its own stack. The GuestThread record itself is kept, so post-exit prio/affinity/name queries still find the handle.
Adds runtime_low_unmap as the counterpart to runtime_low_map.

- Fixed the crash at startup with the pipeline binary cache on NVIDIA 595.x (595.104.02, 595.112.07): vkGetPipelineKeyKHR(device, nullptr, key) returns with rbx, a callee-saved register, set to 1, and the caller crashed when it kept the key pointer there (read of 0x11 in InitializePipelineBinaryCache)
- Added GetGlobalPipelineKey: on x86-64 GCC/Clang a noinline function with an rbx clobber after the driver call, so rbx is saved on entry and restored on return whatever the driver leaves in it
- Only the global key query is affected: pipeline keys with a real pipeline, vkCreatePipelineBinariesKHR, vkGetPipelineBinaryDataKHR, vkReleaseCapturedPipelineDataKHR and vkDestroyPipelineBinaryKHR keep rbx, rbp and r12 to r15 (checked against 595.112.07); 615.78.08 no longer has the bug

- libxess.dll loads only by full path from the game's folders, with the search limited to that

Players on Polaris cards (RX 570, 580 and 590) saw the game close with code 23 on
"SurfaceFormat: Unknown data_format=9 and num_format=7" and similar pairs (6/0, 6/4, 6/5,
10/7, 15/5, 15/7), during area loads and fights. Such a pair comes from a texture
descriptor the game is still rewriting; no real texture has it.
A texture whose pair has no texture format now reads as a null texture, through the
existing "Rejecting invalid T#" path: the texture check accepted any two known values,
even a pair no real texture combines. A null binding now keeps the storage descriptor type
of a storage image (it was written as a sampled image, which Vulkan rejects), and a
rejected T# read with a dynamic mip index fills every descriptor the pipeline reserved for
it (it filled one). A draw whose vertex input has such a pair is skipped too, since no
vertex format matches the shader's input type. A colour target whose data format is a
value the hardware leaves unused (15, 23-31, 42, 43) reads as no target. Any other caller
that still meets such a pair (a colour target, a vertex table rewritten between pipeline
choice and recording) gets the same data format with a number format that exists (Unorm,
then Float, then Uint), which keeps the element size; that draw can read wrong values, and
each pair is logged once. For an integer pair such as 6/5 no integer format exists, so
that draw reads a float format as integers. Real formats are unchanged.
Lineage:
- bloodborne-native/bloodborne-runtime@63f043a272 (Pablo Souza, 2026-10-19): SurfaceFormat falls back to an existing number format
- Supermedo/bloodborne_pc@5a09b8ff68 (ethan, 2026-10-26): the same fallback, written independently, logged once per pair
- bloodborne-native/bloodborne-runtime@e207326050 (Pablo Souza, 2026-11-03): unused data format values read as invalid; a colour target with one is no target
- Final form: bloodborne-native/bloodborne-runtime@e207326050. Not taken: the RemapDataFormat hunk of e207326050, which would pass a vertex input with an unused value to Vulkan as an undefined format (colour targets get the check directly, and textures already reject these values); the SnormNz number conversion hunk of Supermedo/bloodborne_pc@3e3b760fb3 (parsifal295), since no God of War III report shows its stop.
Adapted for SpartanPort: comments tagged spartanport:; textures with such a pair are
rejected in SpartanPort's texture check (IsKnownFormat, vk_rasterizer.cpp), and vertex
inputs in RefreshGraphicsKey (vk_pipeline_cache.cpp), so the fallback does not reinterpret
either; null bindings keep their storage type and mip count; each pair is logged once (as
in 5a09b8f) where the source logs the first eight; new surface-format-test covers the
reported pairs and the colour target check.

RecompLauncher can now set the game up from the player's own dump
folder, show the video settings on the game's page and start it.
The file ships at the top of the Windows zip and inside the AppImage.
Nothing about how the game runs changes.
`SpartanPort --prepare --game <folder>` makes the game image and the
content profile of that folder, as a start does, then stops: no probe,
no window, no game. It prints `progress <0 to 1> <text>` lines and
exits 0, or 1 with the reason. Without the argument nothing changes.
The limiter can present queued requests back to back after a late frame.
Rebase its deadline after a stall and preserve its phase through small wake delays.
Use the runtime high-resolution wait on Windows for both limiter waits.
Keep the live frame and engine limits, and cover queued frames and timer jitter.
Lineage:

Expanding an image uploads current guest memory, then copies the older image over it.
A CPU-dirty source can restore stale texels in the replacement.
Copy only when the source holds clean GPU-written data absent from guest memory, or is
multisampled (never uploaded, so it always reads as dirty). A maybe-dirty source whose guest
bytes are unchanged counts as clean; the replacement is tracked before those bytes are read.
The dirty flags cover the whole image, so a CPU write to one mip would also drop the
GPU-written data of the other mips. A GPU-written source is therefore refreshed first:
RefreshImage uploads only the mips whose guest bytes changed since their last upload and
keeps the others, and the clean source is then copied in full. A mip without a recorded
hash is uploaded from guest memory, as before. Keep rebind handling and the runtime's
existing flag inheritance.
Lineage:
- shadps4-emu/shadPS4@699009c949 (#5444, BeneausVillach, 2026-10-20): guarded ExpandImage copies by GPU-valid source data
- Final form: shadps4-emu/shadPS4@699009c949. Not taken: the sibling dirty-bit-only guard allows maybe-dirty copies; the upstream validity rule is stricter. No later correction was found.
Adapted for SpartanPort: used SafeToDownload, the existing equivalent of HasGpuValidData;
CopyImage already inherits GpuModified and clears Dirty. The source refresh before the check
is new here: upstream drops every mip of a CPU-dirty source.

…reuse
Marking a maybe-dirty image hashes all its bytes, but refresh checks only its corner.
Use one full-range hash on both sides and renew the reference before writes to a clean image.
Record mapped mip references on uploads that may later hold GPU-written contents.
Do not hash unmapped ranges or treat a missing reference as unchanged data.
On a two-page image, take the reference before the first boundary page is unprotected:
CPU writes there no longer fault, so a later hash could already include them.
Never hash a GPU-dirty image: its upload comes from the buffer, and its guest pages may be
read-protected (SPARTAN_READBACKS=2), where reading them forces a synchronous download.
Lineage:
- yumlevi/bloodborne_pc@43fcf95283 (devilismyfriend, 2026-10-04): matched maybe-dirty ranges and recorded upload baselines
- Supermedo/bloodborne_pc@136a72d0c2 (Supermedo, 2026-10-12): limited upload hashing to images the GPU may write
- Supermedo/bloodborne_pc@01b004cc2e (DarkSpartan, 2026-10-12): hashed only fully mapped mips
- Bradley7900/SpartanPort@e3da29ec7b (sourama, 2026-10-27): refreshed the hash of a clean image before the next write
- Final form: Bradley7900/SpartanPort@e3da29ec7b plus the mapped upload hashes above. Not taken: range invalidation in e3da29e is separate; ayozetr/bloodborne_linux@7331bb9410 is outside the permitted licence window; earlier duplicate hash ports are superseded by this chain.
Adapted for SpartanPort: kept the cache's upload and authority paths; returned an absent hash for unmapped whole-image ranges as well as guarding per-mip hashes; omitted the source diagnostic toggle.

A cached child mip or slice can hold GPU-written contents absent from guest memory.
Overlap resolution discards that data when the larger parent has not been allocated.
Create, track and refresh the parent before merging the child. Tracking comes first, as in
UpdateImage, so a CPU write during the upload marks the parent dirty.
Copy the child only when it holds clean GPU-written data or is multisampled (never uploaded,
so it always reads as dirty); a CPU-only or dirty child would overwrite the parent's fresh
upload. A maybe-dirty child whose guest bytes are unchanged counts as clean.
Record the copied mip's guest hash first when the new parent has none (a mip over 64 KiB
with no GPU use yet): without it, the parent's next refresh uploaded that mip again from
guest memory and lost the child's GPU-written texels.
Lineage:
- shadps4-emu/shadPS4@d3ff0e0cc2 (#5433, johulk, 2026-10-19): created the parent before preserving its cached subresources

Adapted for SpartanPort: used slot_images.insert and an inline dirty-source guard; retained target rebind handling, alias logic and existing copy-layer checks; the copied mip's hash baseline is new here, because SpartanPort hashes only tracked mips on upload (RefreshImage).

…ores
With an upscaler on, object motion records every vertex's clip position from the vertex
shader. It wrote the four components with device-scope atomic exchanges on a buffer
device address. On RDNA2 cards (RX 6650 XT, RX 6900 XT in Uncharted ports) the first
submit with these atomics lost the device.
Each component is now written with a relaxed, device-scope atomic store. Invocations that
repeat a vertex in an indexed draw write the same slot, so the writes stay atomic: plain
stores from several invocations would be a data race, which Vulkan forbids even for equal
values. An atomic store returns nothing. Compiled by RADV for Navi 21 (Mesa 25.2, null
winsys), the exchanges become four global_atomic_swap read-modify-write atomics, and the
atomic stores become four ordinary global_store_dword ... glc stores, the same store kind

The source's claim that device-scope atomics are illegal under the GLSL450 memory model is
not repeated (only queue-family scope needs the Vulkan memory model).

A direct copy between D32 and D32S8 depth images is invalid Vulkan and can

…ate pick
`--play --update-dir <folder>` uses the folder as the game update for
that start when it holds an eboot.bin; a skipped pick or a folder
without one leaves the saved update folder alone. Nothing is saved to
settings.json, and without the argument nothing changes.
The ring offset table holds one entry per hardware compute queue (7 pipes of 8 queues),
but the queue slots come from a slot vector that grows. A game that maps more queues
than it unmaps gets slot 56 or later, and the offset reset added for remapped queues then
writes past the table. Such a mapping now frees its slot and returns
ORBIS_GNM_ERROR_COMPUTEQUEUE_INTERNAL before the read pointer or the offset is touched,
with one error log line. Mappings within the hardware count are unchanged.

…parent
Merging a child image into its parent frees the child, but a descriptor already bound to
it kept pointing at the retired image: writes landed there after the merge copy and a later
lookup found the parent's older contents. A bound child is now marked for rebind before it
is freed, as ExpandImage does. This also covers merges into a parent that already existed.
The rasterizer's rebind pass looked up the replacement image with a copy of the descriptor,
which FindImage moves to the child's mip and layer in the parent, but then built the view
from the original descriptor, so it showed the parent's first mip and layer. The pass now
rebinds before it takes the descriptor. This also corrects rebinds after ExpandImage.
SliceOf returned the child's offset divided by the child's whole size. For a child of more
than one layer that is not the parent layer it starts at (a two-layer child at layer 4 was
copied to layers 2 and 3). It now divides by the size of one parent layer, and refuses a
child whose layers would run past the parent's last layer. Single-layer images inside the
parent get the same result as before; the alignment check is unchanged.
The parent's mip reference is no longer hashed when the parent is GPU-dirty: its guest
pages may be read-protected, and reading them forces a synchronous download
(MaybeDirtyHash already skips such images).
Lineage:
- Written for SpartanPort. It completes "Fix(TextureCache): kept child image data when first

invalid, but the draw was still published as ready. That flag also turned off the V#

This PR adds XeSS upscaling and launcher preparation support. It also changes GPU format, texture-cache, memory, and presentation handling, adds tests, and updates guest-thread resource cleanup.
Changes: XeSS upscaling
Layer / File(s)
Summary
XeSS API and Vulkan setup gpu/third_party/xess/*, gpu/shadps4/video_core/renderer_vulkan/vk_xess.*, gpu/shadps4/video_core/renderer_vulkan/vk_instance.*, gpu/CMakeLists.txt
Adds XeSS API declarations and a Vulkan implementation. Device setup queries extensions and features, configures readiness, and retries device creation without patched XeSS features if creation fails.
Routes XeSS through temporal upscaling, adds XeSS settings and controls, and updates TAA defaults and translated descriptions. The launcher adds a Windows XeSS choice and a XeSS-specific hint.

Adds unused-format classification and fallback format handling, rejects undefined surface formats in draw paths, and replaces dirty-register scanning with sparse word iteration. Adds tests for these changes.
Image and texture-cache tracking gpu/shadps4/video_core/texture_cache/*, gpu/VENDOR.txt
Changes image layer matching, exact-address lookup, dirty-image hashing, and parent/child image handling.
Adds an out-of-device-memory allocation retry and lazy page-state chunks. Adds submission locking around selected waits and swapchain recreation, and updates image copies, descriptor handling, FSR reset behavior, and shader stores.
Adds frame-deadline and sleep helpers, uses them in presentation, validates compute-queue slots, and builds and runs the new frame-pacing and register-dirty tests.
Launcher preparation and packaging
Layer / File(s)
Summary
Preparation and update-directory routes launcher-rust/src/startup.rs, launcher-rust/src/main.rs, launcher-rust/src/runner/mod.rs, launcher-rust/tests/*
Adds a --prepare route that prepares game image and content-profile outputs without starting the game. Play requests can use an update directory that contains eboot.bin; tests cover routing, success, and error cases.
Launcher configuration and distribution recomplauncher.json, packaging/fetch_xess.sh, packaging/linux/build.sh, packaging/windows/package.sh
Adds launcher metadata and packages it with Linux and Windows builds. The Windows packaging path fetches XeSS assets at a pinned revision and checks the DLL hash before packaging it with license notices.
Guest thread resource cleanup
Layer / File(s)
Summary
Mapping release and thread cleanup src/runtime.h, src/runtime_memory.c, src/runtime_thread.c
Adds runtime_low_unmap and tracks stack mappings and TLS ownership so cleanup can release resources after joins or detached-thread reaping.

Possibly related issues
FelipePrado0/SpartanPort#1068 — The buffer allocation retry concerns the device-memory allocation failure described in this issue; the summaries do not confirm that it covers this exact allocation path.
FelipePrado0/SpartanPort#1308 — The PR changes TAA defaults and temporal-upscaler behavior, but does not state that it fixes the reported flicker and aliasing.
FelipePrado0/SpartanPort#1016 — The PR changes texture-cache tracking and allocation behavior, but does not state that it changes the reported cache limit.
FelipePrado0/SpartanPort#1142 — The PR changes the same Vulkan pipeline-binary-cache query path described in the issue.
No introduced security weakness was established in the inspected paths. Restricted library lookup, a pinned download, and rendering fallback limit exposure. Concurrent cleanup and interrupted game preparation remain only partially verified.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The added native library inherits the game process’s authority and receives its Vulkan device, command buffer, and image handles. An attacker able to replace the library in an accepted installation location could execute with that process’s privileges; the inspected load path does not derive its location from guest image metadata.
Trust Boundaries and Controls
observed — The new executable-dependency path has two distinct controls: packaging checks the pinned library digest, and runtime loading restricts where the DLL and its dependencies are found. The inspected runtime loader does not repeat the packaging digest check.
Resilience and Maintainability Implications
observed — The ring path newly used by smaller image-copy allocations records scheduler ticks for reservations and refuses overlapping reuse while earlier GPU work remains pending. Ring trimming and dedicated-buffer reuse also check completion. This addresses the staging-lifetime question, but does not establish safety under arbitrary concurrent callers.

The title names five integrated PRs (1170, 1187, 1276, 1294, 1296) under a Validation feature label. The changeset does cover that integration: it spans the NVIDIA pipeline-key wrapper, guest thread stack and TLS reclamation, RecompLauncher prepare and update-dir options, sibling-port GPU fixes, and the TAA defaults and XeSS upscaling. The title is therefore related to the main change. It does not name the main functional changes, so it is only partially descriptive. It also uses 'Feat' capitalization and a generic 'Validation' scope, and lists PR numbers instead of the changes they contain.

Align multi-layer children to a slice, not to the full child size.
For a four-layer parent with slice size S, a two-layer child starting at layer 1 has addr_diff = S and guest_size = 2S. Line 298 rejects this valid child before the new slice calculation runs. Use slice_size for address alignment. Otherwise, overlap resolution can miss the parent image and its GPU-held contents. MipOf permits this one-level child at a slice boundary.

Worker-side vertex-table reads have no fault recovery on dynamic-vertex-input devices.
On dynamic-vertex-input devices, RefreshGraphicsStages reads attrib.GetSharp(*vs_info) at vk_pipeline_cache.cpp:1214. The worker calls this path through PrepareGraphicsPipeline in vk_draw_prep.cpp:460. No sigsetjmp or runtime_fault_recover covers that call chain. The UdPointerNull check at line 1204 tests only for a null table pointer. The worker comment at vk_pipeline_cache.cpp:1308-1311 says these table pointers can be stale by the time preparation runs. A stale nonzero pointer can therefore fault at line 1214 with no recovery scope, and the fault is not caught.
The same unprotected pattern already exists for the same table in PrepareVertexInputs at vk_draw_prep.cpp:480. The new read therefore moves the first fault point earlier on this path. It does not add a new unprotected class of access. A fix must cover the worker preparation reads as a group, not only line 1214. Wrapping only the new call would leave PrepareVertexInputs and PrepareResources exposed.
Install the recovery scope around the worker's guest-memory reads in PrepareGraphicsPipeline and the draw-preparation calls, using the same sigsetjmp pattern as lines 1312-1334. Preserve the cleanup of runtime_fault_recover on every exit path. The exact placement needs the WorkerLoop source above line 440 and the fault-handler behavior. Those were not inspected, so no patch is given.

Staging copies larger than 128 MiB write past the allocation.
CopyImageWithBuffer computes the copy payload but never compares it with the staging range. The fallback in CopyColorAndDepth requests 128 MiB before that payload is known. A copy whose base level is larger than 128 MiB, such as an 8192×8192 four-byte image at 256 MiB, can write beyond the requested range. Mip levels increase the payload further.
Compute the payload size before the staging request, and request staging for that size. Alternatively, split the copy into pieces that fit within the allocation. Keep the direct CopyImage path unchanged for the cases that still qualify for it.

Update CopyColorAndDepth and CopyImageWithBuffer so the copy payload, including all mip levels, is calculated before requesting staging memory and the staging range covers that full payload (or split the copy into chunks that fit). Keep the direct CopyImage path unchanged for cases that qualify.

Pass XeSS inputs on the scaled TAA dispatch.
When XeSS is selected and RunScaled runs, line 2495 calls RecordTaa without XessInputs. The XeSS branch in RecordTaa is skipped, and ordinary TAA runs. RunScaled runs from OnDraw only when Scaled() is true, through scaled_session or a non-1920x1080 target. The default XeSS scene path through RunSceneTaa passes inputs correctly.
Pass the same XessInputs that RunSceneTaa builds at line 1997, adapted to the scaled image handles, formats and dimensions. The inspected snippets do not show every field, so this change needs a full review of the scaled path before it is applied.

Preserve GPU-written layers when another layer is CPU-dirty.
A CPU write to one layer marks the whole child CpuDirty, so SafeToDownload() is false. If another layer still holds GPU-only texels, the parent upload reads stale guest bytes for that layer. This branch then skips CopyMip, and FreeImage retires the child. Reconcile the CPU-dirty and GPU-written layers before freeing the child; a whole-image dirty flag cannot establish that every GPU-written layer is obsolete. (raw.githubusercontent.com)

Capture a large mip’s baseline before its first GPU write.
A large image can upload first as a sampled texture with mip_hashes[m] == 0. A later storage binding sets GpuModified without hashing that clean mip. If the GPU writes that mip and the CPU dirties another mip, the new ExpandImage source refresh treats the zero baseline as a changed hash. It uploads stale guest bytes over the GPU-written mip before copying the source. Record the guest baseline before the image becomes GPU-writable, including mips larger than 64 KiB.

Synchronize XeSS status text between recording and the overlay.
TemporalUpscaler::RecordXess writes xess_problem (vk_temporal_upscaler.cpp:1177 and :1184). SpartanOverlay::ImageTab reads it (spartanport_overlay.cpp:620) during SpartanOverlay::Render, which runs on the presenter path (vk_presenter.cpp:898 and :1084). The field is a plain const char* (spartanport_settings.h:174). The write does not take imgui_mutex, so the two accesses do not synchronize. Draw recording and presentation run on separate threads, so this is a data race.
The rotating kept array adds a lifetime hazard. kept[next] = shown can free text that the overlay still reads, if four later problem changes reuse the same slot during one InfoRow call.
Make the write and the read use one lock. Give the status text owned storage that the lock protects. An atomic pointer alone does not protect the reused strings. Expose a small setter from spartanport_overlay.cpp, because imgui_mutex is private to that file, or use a dedicated mutex shared by both paths.

Preserve caller-relative game paths in AppImage preparation.
For spartanport-x86_64.AppImage --prepare --game ./dump, packaging/linux/AppRun changes directory before forwarding the arguments. This relative path then points inside the mounted package, not the caller's directory. Preparation reports a missing eboot.bin even when ./dump is valid. Resolve the path against the original working directory before checking or preparing it. Absolute paths from the metadata avoid this failure. (raw.githubusercontent.com)

Relabel the mouse-only sensitivity control and correct its help text.
The control writes mouse_aim_sensitivity, which the settings header documents as L2 aim with the mouse. Controller input does not use it. The label "Right stick sensitivity" and the help text "How far the camera turns for the same stick movement" suggest that the control changes physical stick sensitivity. Players with a controller can then expect a change that does not occur.

Depth copies between different depth formats reinterpret bits and read unwritten staging bytes.
ResolveDepthOverlap recreates a depth image when a requested depth target differs in stencil presence or bits per texel. It then copies the old image into the new one through CopyColorAndDepth. A D16 cache image and a D32S8 target take the buffer path, because their aspect masks differ.
The download writes two bytes for each D16 texel. The shared footprint reserves four bytes for each texel, and the upload reads that full footprint. For a D16 → D32S8 copy, the upload then reads two bytes the download never wrote. The depth value is also wrong even when every byte is written, because the buffer copy transfers raw bits without converting between depth formats. Zero-filling the extra bytes would not correct the value.
The fix is not a localized edit. Either convert the depth values with a path that handles format conversion, or send this format pair through a different recreation path that does not stage raw bytes across formats.
