Comment 2 for bug 1818494

It has happened a couple of times. Maybe a coincidence with the zoom. I had Firefox and a terminal open as well as Widelands (not fullscreen. I'm sorry I do not have the saved game but it didn't crash when played. Perhaps I'll compile a more debuggable version and see if I catch it again.

Probably not too helpfull but:
