KWin crashed again, this time with kate. I closed kate and switched virtual desktop to post the output here und KWin crashed again. The Backtrace is the same.
It's not a real problem, because KWin starts again immediatly. But it's still a bug, so i reported it.
Opening as debug information is provided.
If you disable the fall apart effect, can you reproduce the crash?
No, I cannot reproduce the crash without the fallapart effect. The Crash happens during the fallapart effect, when switching virtual desktop.
