Public bug reported: It's a bit unclear which program is causing this, but here it goes:
The top left corner of my left screen (dual screen setup) has a white rectangle. Using xdotool doesn't really give me a proper PID, since it yields the PID of the main nautilus window (the desktop): $ xdotool selectwindow getwindowpid findclient: 18874372 findclient: 18874372 21792 hildeb 21792 0.2 1.3 1526528 47448 ?
