-- Information about the crash:
- What I was doing when the application crashed:
I opened dolphin, then opened image and gwentviewer window captured screen, but image didnt show. Dolphin stopped too. 
- Custom settings of the application:
I used intel graphics and was watching video in VLC (revision 3.0.9.2-0-gd4c1aefe4d). Without VLC all works fine
