Works for me (emacs trunk rev 105334)

Note this feature depends on compositing being active: all it does is 
set the relevant x11 window property to request the compositing manager 
render the window with some alpha.  So it has no effect if you've, say, 
turned off compositing (sometimes called "desktop effects") in a window 
manager capable of it (say XFCE), or have switched to a low-requirements 
desktop environment / window-manager that doesn't do it at all.
