Bug ID: 56478
           Summary: Requesting sub HD fullscreen resolutions breaks
                    applications/games on Apple Silicon
           Product: Wine
           Version: 9.5
          Hardware: aarch64
                OS: MacOS
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P2
         Component: winemac.drv
          Assignee: [e-mail]
          Reporter: [e-mail]

Apple Silicon equipped Macs do not support "legacy" low (virtual?) display
resolutions anymore. Due to this several old Windows games running through wine
are broken, even though they run perfectly well otherwise.

Resolutions like 800x600px and lower are definitely effected, though I think
this applies to anything below 1024x768px.

A possible but undesired workaround is falling back the legacy X11 (XQuartz)
environment and its virtual desktop mode or using windows side tools which
enforce executables to run in windowed mode (like Dxwnd).

To my knowledge implementing something like the before mentioned virtual
desktop mode isn't feasible on macOS as child windows aren't supported.

Therefor I propose the solution, that the winemac.drv should ignore
wine/windows API "fullscreen calls", if the desired resolution is below
1024x768, when running on Apple Silicon. While this might break wine's
philosophy regarding windows function parity it would allow older software to
"just work" again without any manual workarounds.

An effected windows game would be "Colin McRae Rally 2005" which got a Demo
available. Further information, documentation and links regarding this issue

That’s what the log prints after failing to set the natively unsupported Screen
resolution:

0104:err:system:NtUserChangeDisplaySettings Changing L"\\.\DISPLAY1" display
settings returned -1.

@Fabian Maurer: how is it not a blocker? It stops otherwise fully working
programs from being usable. Programs that even work on the same OS when run on
different hardware.

@Ken Sharp: I tested with several versions from the 8.X series, as well as 9.X
until 9.5 versions of wine. I can test newer releases when I got some time.
