I can confirm this (mis)behaviour with matplotlib 0.80 and gtk+/pygtk 
2.6.  I had wanted to look into this matter, but didn't yet have time to 
do it.  A simple guess would be that the expose-event is not handled 
properly by the GTK backend.

I noticed the problem when I put a menu-bar over a matplotlib GTK 
Canvas.  When you leave an opened menu, the menu will not disappear.
