Description Franz Trischberger 2020-11-24 06:14:31 UTC

Since updating Qt to 5.15.2 yesterday I got kwin crashing twice when I was typing in brave browser. It obviously doesn't crash reproducably. The backtrace was the same both times:

Application: KWin (kwin_x11), signal: Segmentation fault

Unfortunately archlinux has no (easy) way to install debug libs, so this probably isn't useful.

This bug was reported against an outdated version of KWin. We have made many changes since the. 
If the issue persists in newer versions can you reopen the bug report updating the version number.
