Public bug reported:

Hi there,

i have a 2 screen configuration with LVDS1 as Main display and VGA1 on top of LVDS1.
there is a very annoing bug in X.Org... 

you can see it, if you try to maximize a window on the top screen, which has a higher resolution as the bottom screen.
The problem you can see the effect here: http://www.flickr.com/photos/64718250@N04/
i do not know how to describe :(

but the problem is, that i cannot maximize a window on the top screen
