Hi,
  I noticed that certain guests (for example, Ubuntu 9.04, Ubuntu 9.10,
and the Ubuntu 10.04 release candidate) show dramatically (~100x) slower
graphical output when running under qemu-kvm-0.12.1.1 than under qemu-kvm-0.11.1.
Other guests, notably Windows XP and Windows Vista, run fine under both
version of qemu.  The regression is still present in qemu-kvm-0.12.3.


Please post kvm_stat output for the fast and slow cases (preferably running the same workload, perhaps a web page displaying an animation).

I have a truly marvellous patch that fixes the bug which this
