Bug ID: 48158
           Summary: Starfighter 77 doesn't run properly in fullscreen mode
           Product: Wine
           Version: 4.20
          Hardware: x86-64
               URL: https://papptimus.itch.io/starfighter-77
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: Mint

The game defaults to fullscreen but it doesn't work properly and instead
displays two instances of the game running simultaneously. Pressing F4 switches
to windowed mode and it then works OK. Pressing F4 again makes the display
disappear off the screen.

This happens with both Nvidia and AMD.

Can't see any obvious errors.

Sorry, can't run regression test.
