Bug ID: 54069
           Summary: ddraw:ddraw7 - test_texture_wrong_caps() sometimes
                    fails on Windows 8+
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: d3d
          Assignee: wine-bugs@winehq.org

ddraw:ddraw7 - test_texture_wrong_caps() sometimes fails on Windows 8+.
ddraw7.c:18954: Test failed: Got unexpected color 0x00000040.
and
ddraw7.c:18972: Test failed: Got unexpected color 0x00ff00ff.
See https://test.winehq.org/data/patterns.html#ddraw:ddraw7
Notes:
* There is no evidence of this happening on Windows 11.
* This seems to only happen with Microsoft's "Microsoft Basic Display Adapter" 
driver: the "-1qxl" and  "-2qxl" (dual-monitor) configuration use the "Red Hat
QXL controller" driver and are are not affected. Neither are the AMD / NVIDIA
PCI passthrough configurations.
* The 0x00000040 result mostly happens on Windows 8 to Windows 10 1607 but it
also happened a couple of times on Windows 10 21H2. Meanwhile the 0x00ff00ff
result seems to only happen on Windows 10 2004+.
* ddraw:ddraw1, ddraw:ddraw2 and ddraw:ddraw4 have a similar test function but
don't have this failure.
