--- Comment #8 from tempel.jul...@gmail.com --- Found the cause of the issue: It sits in front of my PC. The issue is caused by setting KWin to always keep window thumbnails, not just for shown windows. At this occasion, I also found out that the Proton fullscreen hack also automatically tells KWin to resume compositing when minimizing a game. Though e.g. the native Linux port of Shadow of the Tomb Raider by Feral doesn't do this. -- You are receiving this mail because: You are watching all bug changes.
