Bug ID: 55986
           Summary: Gunner3 has flickering in fullscreen
           Product: Wine
           Version: 8.21
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

      Distribution: ---

Since wine-6.1 there is flickering when running Gunner3 in fullscreen mode.
Also, from time to time old frame data is shown for a few moments making the
game
It works with winecfg virtual desktop mode, and making screenshots in
fullscreen is hard. It looks similar to the glitches in bug 45168 (but it is
unrelated).

Don't try to click on a level without having the fix from bug 41977 though, it
might crash. The menu is enough to reproduce the issue.
