STEPS TO REPRODUCE
1. 3 external displays, FHD
2. Login screen appears, credential entered
3. Displays going off for awhile, resolution switching....
4. Displays are back, desktop appears, each display has its own wallpaper set.
When crash occurs, one of display is just black background (but panel is
visible), for instance display no.1.
5. Left mouse click to black area of display no1. , some wallpaper image
appears, sometimes diffent one than before, and sometimes for instance
wallpaper of display no.2. is changed also to different picture at the same
moment. Another click and wallpapers are changing again. It tooks about 3-5
clicks, then all displays are correct, working and wallpapers are properly set.
(weird behavior that because of this crash, the wallpapers are changing so...)
6. Meanwhile the crash report window pops up.
OBSERVED RESULT
Wallpaper of desktop of one of external displays is missing, wallpapers are
changing by just clicking to empty desktop area. Crash report of plasmashell
appears.
