The last thing I'll add for now is that my bug, the black pixel noise (fills the axes window when motion starts in a zoom-to-rect event) which may be unrelated to your bug, is happening in backend_gtk.NavigationToolbar2GTK.draw_rubberband in the pair of calls: # this is used to copy the background that the zoom to rect "rubberband" will be drawn over self._imageBack = axrect, drawable.get_image(*axrect) # this is used to restore the background before redrawing the rectangle for the zoom box drawable.draw_image(gc, imageBack, 0, 0, *lastrect) Since the bug is only exposed when a combo box is added to the hierarchy, and appears to be platform or gtk specific, I'm suspecting a gtk bug at this point. But I don't have anything conclusive or a minimal example which I could use to post to the gtk list. The mpl calls and values (axrect, lastrect, etc) look correct on inspection. Somehow the call to drawable.get_image is getting a buffer full of noise if and only if the combobox is added to the vbox.
