Comment 1 Milan Bartovic 2020-02-03 21:08:32 UTC

After a next Sleep (Suspend to RAM):
KWin Window Manager
Desktop effects were restarted due to a graphics reset

System is DELL E6420.

Comment 2 Milan Bartovic 2020-02-03 21:10:12 UTC

Next sleep produced again:
KWin Closed Unexpectedly.

Comment 3 Milan Bartovic 2020-02-03 21:16:45 UTC

No KWin crash directly after reboot.
But another crash after sleep.

resumed laptop from sleep, logged in

- Unusual behavior I noticed:
lockscreen shows static pattern instead of image
