The attached patch will prevent showing notifications when a window on the
screen is in fullscreen-mode. It's not perfect, it's just skips displaying the
notification instead of postponing it.

use wnck and don't show notifications if another window is fullscreen
The size-checking (workaround comment) is for the bug:
in libwnck that is already fixed in cvs. So it's probably save to remove it and
just use is_fullscreen(win) without additional checks.
Do you still experience this issue with newer soft?
