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.

It's almost certainly direct scanout kicking in when the cursor is hidden, but just to make sure, please set https://invent.kde.org/plasma/kwin/-/wikis/Environment-Variables#kwin_drm_no_direct_scanout and check if it still happens with that

I am now back to kwin 6.3.3-1.fc41 Is this something that can be fixed so I don't need to have this environment variable?
