Some info I would suggest including for issues like these are exact steps to reproduce (i.e., commands that you run), and where appropriate, a photograph of the screen. In this case I think there's sufficient info to guess at both of these, but in general those would be helpful.
Also, I've been backporting a lot of fixes to xserver in the past weeks. I don't know if any would fix this specific issue, but it would be helpful if you could re-test with the latest updates to ubuntu.
Thanks. I've filed this upstream.
