Having the same problem i think, though its really minor. 3 or four times since i upgraded to 12.04 the day before yesterday and i think its just in firefox (though i've been using that most of the time so that can be the reason). One time it was just the X:s that you close the tabs with that were bad. It seems to be confined to a certain "texture", for example one time it was in the main browser area but followed the page up when i scrolled down and dissapeared when i scrolled back up.
