I did some tests on my laptop:
  - kvm.git + mst's patch
  - qemu.git (upstream qemu)
and still got graphics curruption.


Corruption:
  On usual Desktop environment, I opened two terminals on different
  workspaces. Then as Jan did, I did "find /" loop on both of them.

  During these heavy updates, I tried to switch between these
  workspaces some times. Then, at some turn, some part of old
  workspace's images like terminals and mouse cursor remained
  in the new workspace.

  I could refresh these by moving mouse over the problematic parts.
  But without doing so, the images remained still.


Refresh is not working on virtual machines as I expect?


Thanks,
  Takuya
