-- Information about the crash:
- What I was doing when the application crashed:
I logged in to plasma from SDDM. Then I directly changed to the virual console
tty2 with the keycombination "Ctrl+Alt+F2". After that ein directly changed
back with "Ctrl+Alt+F1". There I got the message that KWin has crashed.
I'm using antergos (up to date as of today 2019-01-11) with the nvidia driver
415.25-5.
The crash can be reproduced every time.
