I've managed to work out all the bugs with Xvnc + Composite, except for one.
When moving an X window around I get rendering errors. F8->Refresh doesn't help
(which means its something being done in the Pixmap layer) but minimizing and
restoring the window resets it back to normal.
Here is what it looks like, in case anyone's interested.
