Virt-manager guest window does not refresh

[Spixi]

Hello,

I have a big problem and was unable to find a solution on the Internet. I am trying to set up a virtual machine with Windows 8 using qemu-kvm and virt-manager.

But no matter, whether I use vnc or qlx/spice the screen freezes and does not refresh (see attached screenshot). The only possibility is to close the guest window and open it again. What do I have to do that the screen properly refreshes?

For information about my system see here.

Thank you in advance.

I have the same behaviour too. And it doesn't depend on what guest OS I run (I have several different linux distros).
