My observations (using firefox 3.6.13 and nvidia 260.19.06)

- The problem only happens on launchpad.net. None of the other examples given on this bug still exhibit the problem. Likely they were all caused by the old slow javascript engine that was replaced in a version of FF since 3.0. But the launchpad problem is different because:
- The problem still happens even when javascript is disabled, but it does not happen if you save the HTML of a launchpad bug and load that.
- The problem gets worse as the firefox window becomes larger. This would seem to imply something is causing too many fullscreen repaints.
