-- Information about the crash:
Attempted to fix display layout which was reset after reboot due to
https://bugs.kde.org/show_bug.cgi?id=451591
The alignment between two adjacent displays was a bit off so I tried to
slightly readjust it by moving one display in the layout. The new alignment was
not like intended so I attempted to revert it by clicking the revert button on
the popup that is shown after making a display layout change. The display
layout was reverted to the original after the screen froze for a bit. After
this, the display layout system settings window did not show the usual layout
settings but was mostly blank with only a light blue stripe shown at the top of
the window. (The blue stripe looked similar to an information popup, but did
not display any text). When attempting to interact with the window and click on
it, it crashed and popped the bug report screen.
The reporter is unsure if this crash is reproducible.
