I have a dual-monitor setup (dell laptop and dell external monitor), using
nvidia M120 card (or N120?). When I drag an application window from one monitor
to the other, the screen freezes for a second and I get a popup about KWin
crashing. Here is the backtrace from the crash handler:

Application: KWin (kwin), signal SIGABRT
