--- Comment #17 from andreas.d.k...@gmail.com --- I'm on Manjaro with KDE 5.20.5 and experience the same. I also have this problem after my screen went to sleep. With enabled "Background contrast" desktop effect the problem is gone. I execute `kwin_x11 --replace &` each time after it happens to restore compositing. I'm using proprietary Nvidia drivers. -- You are receiving this mail because: You are watching all bug changes.
