Bug 504760

SUMMARY
when pressing "print" button on keyboard, nothing happens. 
This behaviour is only happening, if a display is mirrored, and the origin display (2560x1440) has a lower resolution as the display (3840x2160) which mirrors the origin display.

when disabling the mirror, everything works again.

STEPS TO REPRODUCE
1. have one display mirrored another with a different display resolution 
2. try to take a screenshot
3. crash


OBSERVED RESULT
crash

EXPECTED RESULT
opening spectacle
