> This fails on a Windows 11 VM with WARP with:
shader_runner:1214: Running tests from a Windows cross build
shader_runner:1216: Compiling shaders with d3dcompiler_47.dll and executing with d3d9.dll
shader_runner:95: Driver string: d3d10warp.dll.

shader_runner:99: Using WARP device.
shader_runner:248: Section [texture 0], line 8: Test failed: Failed to map texture, hr 0x8876086c.

and than it segfaults.

Not sure what's going on here, but apparently the second (i.e., when mapping the smaller level) `LockRect()` calls fails with `D3DERR_INVALIDCALL`. Did you test this on Windows?
