Hang of QXL driver on high resolution screen on windows 7
I use frequently 4k screen for my virtual machines. To get it working, I have to set vgamem="32768" as parameter of QXL driver. When I do it, my machines suffer of random hanging of the display. When it happen, I cannot do anything with the machine, except forced shut down or shut down from virsh using shut down comman with mode=agent. I can also ping the machine, which means, that machine is still running. When hang off, machine cannot be connected via rdp too.
The problem doesn't occur, when I set up vgamem="16384" and connect via spice. The problem doesn't occur, when I set up vgamem="32768" and connect via rdp.
