What

A storage-image lookup without a precomputed surface size checked only its first byte against native multisample owners. A native depth surface inside a larger cached view was missed, so the cache could return stale guest bytes and keep the overlapping native owner active.

Resolve the viewed surface's complete size before the overlap check and use that range before either the native-depth storage path or a cached storage lookup. The regression seeds a cached linear view, creates an unwritten native multisample depth surface inside it, checks a disjoint view ending at the depth boundary, then requires the complete view to retire the intersecting owner without changing guest bytes.

Tested

Windows 11 Pro build 26300, WinLibs GCC 15.2.0, Release, NVIDIA GeForce RTX 4070 Ti SUPER, NVIDIA 617.42.

• Red: the added GPU case fails with a cached storage view kept a native depth owner inside its range.
• Green: native depth and depth-storage dispatch checks pass, including the new cached-view/boundary case. Final integrated validation: 47 selected checks, zero failures/skips; full Windows Release build passes.
• Vulkan required, shader caches disabled and actual Khronos instance/device validation layer insertion confirmed. No new VUIDs.
• The new case uses an unwritten depth owner; it does not require the pending written-depth publication feature. The local PRAGMATA integration also contains perf(agc): defer pipeline artifacts with first-use preparation #6743, fix(agc): enable independentBlend for color targets with different blend states #6782, fix(agc): keep buffer owners when a staged address space dissolves #10304, feat(agc): export stencil operation values through an attachment #10351 and feat(agc): publish a written native multisample D32 depth surface to its guest planes on access #9950; none is included in this two-file PR.
• Conventions and whitespace pass. Game retest pending; no gameplay or performance claim. Full CTest suite not run.

Overlap review: 31 shared-file PR diffs checked. #10049 adds overwrite coverage while retaining the one-byte fallback; this fix uses the complete span and needs a small textual merge with that call-site change. #10064 changes committed 3D slabs. The native-depth fixture additions in #6808/#9950 cover other behavior. None implements this full-span check.
Independent validation of the published commit: Published head 87bdf5445d747ddc76f0cedcb31579e9900aa9c1: full Windows Release build and native multisample depth, depth-storage dispatch, native-depth BDA clear/retirement/clear/refusal checks and patched-library validation pass on a clean tracked tree without overlays (7/7, zero skips). Vulkan is required, shader caches are disabled, and loader logs confirm actual Khronos instance/device validation layers; no VUIDs. Hardware and toolchain are the Windows/NVIDIA configuration listed above. This independently validates the published commit in addition to the earlier integration runs. The complete CTest suite was not run.

Reviewed current head 87bdf54. Resolving viewedBytes before RequireNoMultisampleTarget closes the first-byte-only gap for callers that have not precomputed a surface size, and the check now precedes both native-depth storage handling and cached lookup. The regression exercises an overlapping cached range and an adjacent disjoint range ending exactly at the native depth boundary, then checks owner retirement and byte preservation. The author reports 47 focused Windows GPU checks with Vulkan required, shader cache disabled and validation layers confirmed, no new VUIDs; I did not run the GPU test locally. Hosted eligibility, conventions, intake, labels and report pass; product jobs are skipped by path policy. git diff --check upstream/main...upstream/pr/10368 passes. I found no blocking issue.

Intel run, a second vendor next to the RTX 4070 Ti SUPER.

Setup: Intel Arc Graphics (Meteor Lake, 0x7d55, Windows driver 101.9150), Windows 11 Pro 10.0.26300, WinLibs GCC 15.2.0 r7, Release. Head 87bdf54 was merged into main ec5b89a (clean merge). Environment: ANYPS5_REQUIRE_VULKAN=1, ANYPS5_NO_SHADER_CACHE=1 and VK_INSTANCE_LAYERS=VK_LAYER_KHRONOS_validation (1.4.363). The run uses ctest -R 'native_multisample_depth|native_depth' -j1 -V.

• Results. This PR passes 5 of 5 and main passes 5 of 5. Neither log has a VUID- line or was not found but was requested.
• The new case runs on this device. agc_driver_native_multisample_depth prints cached storage span retires only intersecting native depth owners, which main doesn't have. Its other lines are the same as on main, apart from the storage upload log lines of the new case.
