Problem behavior still exists. Tested with both nVidia (nonfree-bin driver) and intel systems running fully up to date Natty beta2 installs.
Disabling the fade animation on the menus mitigates the problem, but it seems to only be removing the extra 80ms that the menu would normally be fading out. The white boxes are definitely still present when switching between menus rapidly with the fade animation disabled.
