Bug ID: 53500
           Summary: PixelFormats PFD_GENERIC_FORMAT flag doesn't get set
           Product: Wine
           Version: 5.0
          Hardware: x86-64
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

If you grep through the Wine source, you can see that it never sets the
PFD_SUPPORT_COMPOSITION flag, under any of the graphics drivers.

On macOS, the winemac driver never sets PFD_GENERIC_FORMAT so OpenTK treats all
modes as accelerated.

This causes programs such as an older version of BizHawk for macOS (
https://github.com/TASVideos/BizHawk/releases/ ) to fail and even some more
recent software that uses the OpenTK library.
