Description
I have Windows 10 host with Ubuntu 16.04 guest. With enabled 3D acceleration (which is required because without that everything is laggy) and external monitor connected (tested with dvi and mini display port), the drawing on virtual screen freezes when in gnome. It does not matter whether monitor is an extension, clone or primary display. Immediately after monitor disconnection, the virtual screen starts to repaint.
Under the frozen screen the system is running (cursor changes with the windows even after repositioning which is not visible on the frozen screen, ctrl alt fx can be used to display working and visible shell).
When 3D acceleration is disabled, screen repaints fine with external monitor connected. I tested also development version 5.97 with the same result.
