-- Information about the crash:
On each first login after boot my external monitor becomes black, without wallpaper and also there is no context menu. To fix this issue I need to unplug HDMI cabel from laptop and plug-in again. Also during this process I've got plasma crash.

The crash can be reproduced every time.
