Bug ID: 53229
           Summary: dxgi:dxgi - test_swapchain_window_messages() sometimes
                    gets an unexpected WM_DWMNCRENDERINGCHANGED message on
                    Windows
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: directx-d3d
          Assignee: wine-bugs@winehq.org
          Reporter: fgouget@codeweavers.com
dxgi:dxgi - test_swapchain_window_messages() sometimes gets an unexpected
WM_DWMNCRENDERINGCHANGED message on Windows:
dxgi.c:5822: Test failed: Got unexpected message 0x31f, hwnd 00000000010E01E4,
wparam 0x1, lparam 0.
https://test.winehq.org/data/patterns.html#dxgi:dxgi
Where 0x31f == WM_DWMNCRENDERINGCHANGED.
This failure only happens on Windows 8 to Windows 10 1909.
The window handle also interferes with the TestBot's old failures detection.
Even without it, it would have an elevated risk of causing false positives due
to the test's multi-threading (see bug 53212).
