Since last Update via repository, I have blank white/grey squares
overlaying any other windows. Those belong to jitsi as they go away when
I close the program. They differ randomly in size, number and position.
OS: Ubuntu 14.04 with Gnome Desktop
Nvidia Graphics (650 gtx, 4 screens)
Screenshot can be done if this helps.
