I believe there is a long thread on the XFree86 5.0 features. I read it 
but don't recall what was said about translucent windows. Keith Packard 
is certainly working (or worked) on it.

Qt does not have transparent windows. What it currently does is a hack 
that was already mentioned in this thread (screen-grab the background, 
composit). It artifacts in a very bad way if the windows behind the menu 
aren't completely static. There is a similar hack for alpha-composited 
dropshadows for menus in Gtk.

IMHO, this discussion doesn't really belong to Gtk development - X 
really must get the needed functionality. And the needed functinality is 
pretty nontrivial to do (check Keith Packard's homepage for his 
discussion on the issues involved. He also mentions his prototype server 
with translucency and protocol extension proposal).
