I am also affected by this bug, but I have radeon graphics on my desktop (Kubuntu 12.04, Intel i750, Radeon 4890). I had the same problem in Kubuntu 11.10 and also in Ubuntu 11.10 - it was one of the reasons why I used Catalyst before (it was not affected). Later I started using opensource radeon driver and learned to live with this bug.
I have also found that people with intel graphics have the same problem: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/653815 I can also confirm that workaround posted by jones works.
