Reproduction

  • Have a 4k monitor
  • Launch the game
  • Options->Video->Resolution: 1920x1080
  • Options->Video->In Window: no

This game has a native port, but it is almost unplayable because of graphical glitches, so I run the game using Proton.

Update: Actually I just tested and this happens regardless of your monitor resolution. Even if you have a 1080p monitor and select a lower resolution this problem occurs.
