Problem:

On one radeon 7500 compiz when maximizing, compiz does not make the window
bigger than 1024x768 eventhough the screen is 1600x1200. It is suspected that
the chip's limitation on texture size is the reason this happens.

Note though that nautilus and gnome panels are initially size correctly
eventhough their windows are bigger than 1024x1024. If a panel is moved, it does
get resized down to 1024x32.
