-- Information about the crash:
This crash occured when I try to figure out activities. I have a dual monitor set up. I choose "Zoom out", then wanted to "Zoom in" again, but I couldn't find a way to do so. I somehow clicked around in order to find a way to get back on both screens. Then the crash occured.

 -- Backtrace:
