Description
After some time on my booted KVM/QEMU VM the screen becomes black and a lot of letters becomes invisible (please see screenshot in attachment). Also it could happens quicker if to run firefox, load some web page and to move scrollbar up and down. Sometimes it is even hangs the hole VM if to move scrollbar. Relogin always fixes the screen.
