--- Comment #19 from nttkde <watisthis...@outlook.com> --- I have noticed that over time Plasma rendering gets more sluggish (overall low framerate, things like menu item highlight changes etc. behave sluggishly) and that seems to be when I really start getting the black windows too. The Xorg process will have high CPU usage when doing something like playing a video in Firefox (but not when I'm not doing anything on the desktop). Not sure what is cause and what is symptom in this case though. In my case running kwin --replace fixes the sluggishness, Xorg CPU usage returns to being always at low levels and windows seem to render normally again (at least until things start slowing down again). -- You are receiving this mail because: You are watching all bug changes.
