Bug ID: 53255
           Summary: d3d11:d3d11 sometimes crashes in test_generate_mips()
                    on Windows 7
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2

d3d11:d3d11 sometimes crashes in test_generate_mips() on Windows 7:

d3d11.c:30128: Tests skipped: Skipping test with DXGI_FORMAT_R8G8B8A8_UINT on
WARP.
d3d11.c:30128: Tests skipped: Skipping test with DXGI_FORMAT_R8G8B8A8_UINT on
WARP.
0d28:d3d11: unhandled exception c0000005 at 7FF9615D

https://test.winehq.org/data/patterns.html#d3d11:d3d11

Notice that a normal run has 4 of these skip messages instead of 2 which
suggests the crash happens in test_generate_mips().

There are two known instances of this crash:
* 2022-05-03 on w7u-2qxl
* 2022-06-22 on w7u-pt-PT
This makes this a pretty rare failure which can cause false positives.
