Description timn1991 2008-06-15 11:52:40 UTC 
Please describe the problem:
When I resize a window to more than double the width of my screen (1650 pixels) the window decoration gets broken.

Steps to reproduce:
1. Resize a window to a width of some thousand pixels by dragging it to the border of the screen and resizing it multiple times.
2. If it is not broken yet, try to move another window over the window decoration. When the other window is gone, the decoration is gray.

Actual results:
Broken window decoration (see screenshot)

Expected results:
Not broken window decoration

Does this happen every time?
Yes. But sometimes it only happens when you drag another window over the decoration.

Other information:

The Firefox logo in the window decoration is doublicated and some areas are grey or brown.

System: Ubuntu 8.04, GNOME 2.22.2
Driver: fglrx (but no Compiz!)

Bug is probably described in:

 https://bugzilla.gnome.org/show_bug.cgi?id=630203#c25

meta_frames_paint_to_drawable() clips a region to paint in window coordinates against the screen size in absolute coordinates, so if a window is bigger than the screen, and not at 0,0, then we'll clip drawing that shouldn't be clipped.
