Bug ID: 46566
           Summary: Unity games fail to start with wine 4.0
           Product: Wine
           Version: 4.0-rc7
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: winevulkan

Unity games fail to start with wine 4.0-rc7 or Wine 4.0 stable, but they run
with wine 3.21-staging without any problem.

I use DXVK 0.96 BTW, but I don't think that this issue is related to DXVK,
because not all the games that I tested are DX11, some of them are DX9. In
addition, DX11 games that aren't unity games runs without any problem.

The list of unity games that I tried:

Cuphead
Distance
Life is Strange
Ori and The Blind Forest - Definitive Edition

The error that I get:
