Screen corruption under KVM with Spice display

Bug description:
I was experimenting with Ubuntu MATE, and I found severe screen
corruption whenever I run the image under a KVM virtual machine. I
attached a screenshot. I don't think the problem is Ubuntu MATE
specific. I also found it doesn't depend on the display manager. (It
can be either LightDM or GDM.)
Reproduce instructions:
1. Boot up a KVM virtual machine with an Ubuntu Vivid Vervet image.
2. Put some stress on the display: what I used to do is to launch Firefox and
htop in a terminal, then lock the screen, or let it lock by itself.
3. Wait a little, then unlock the computer.
4. You'll see letters missing and images corrupted, like on the attached
screenshot.
