Description Kai Uwe Broulik 2019-07-08 08:26:37 UTC

After latest updates. It crashed four times in a row, i.e. also when it tried to autorestart until it gave up. I then started openbox, restarted kwin, and the problem went away and hasn't come up since.

Like after distro updates?

Does KWin still crash after resume?

Comment 2 Kai Uwe Broulik 2019-07-08 13:31:30 UTC

Probably ABI mismatch after system update

kwin_x11 (5.17.3) using Qt 5.13.2

- What I was doing when the application crashed:

Notebook working on battery go to suspend after some time of non activity. After run system again, this occured.
