Got into this issue.
After running Warhammer II on Lutris got into trouble.
Everything starts to lag, the sound keeps going, but video, after the first loading screen (before video-entrance being played) is not working.
Mouse cursor is present
Link to pastubuntu with terminal output and lutris --subit-issue

Maybe something wrong with my vulcan installation?
All the best,
Alex
