Thanks for looking!
So this is an XFCE sillyness only, other compositing WMs don't suffer from it?


I think it's to do with the X11 compositing manager, even if the window
manager is not intervening. The property needed (_NET_WM_WINDOW_OPACITY)
is standardised (I think), it's just that it doesn't appear in the current
doco on standard WM properties (ie. 
<http://standards.freedesktop.org/wm-spec/wm-spec-1.4.html>),
and it should help with all the compositing WMs.
