Accepting that my bug duplicates this one, then it's not specific to the video driver (mine is an Nvidia GEForce MX 4000).
Removing compiz as Davide suggests fixed it for me also. I'd suspect a race condition involving compiz and gnome-panel, and perhaps all these other variables are just things that affect the timing.
