Bug 501638

SUMMARY

Screen flashes white/brighter when clicking on non-screen elements of Final Fantasy XIV when running versions KWin newer than 6.3.0-3.fc41 or newer, downgrading to Kwin 6.3.0-3.fc41 resolves the issue.

Game is in full screen or borderless windowed. this issue does not occur when playing the game in windowed mode.

Have already tried running latest-git versions of mesa, downgrading, etc., the only thing that resolves it is downgrading to kwin 6.3.0-3.fc41


STEPS TO REPRODUCE
1.  Install kwin.86_64 6.3.0-3.fc41
2.  Launch Final Fantasy XIV
3.  Screen flashes white/brightens when clicking mouse

OBSERVED RESULT
Screen flashes white/brightens when clicking mouse

EXPECTED RESULT
Screen doesn't flash white/brightens when clicking mouse, same as kwin 6.3.0-3-fc41

SOFTWARE/OS VERSIONS
Linux: Nobara 41 (Fedora base)

ADDITIONAL INFORMATION
Attached are my system specs and a video of it. I've recorded using my phone as that seems to show the issue more clearly than a screen recording.

Let me know if you want it uploaded anywhere else.
