@andrew: I may be wrong, but I think you are experiencing a different bug. Does your mouse cursor behave like the video in comment #15?
Nobody has reported seeing this bug since Oneiric, and it went away for me when I upgraded my Natty X server to the version used in Oneiric. So, I believe this bug was fixed in Oneiric. If you are experiencing this exact same bug, that's unfortunate and surprising news.
