Comment 147 for bug 734908

Comment #96 lists this bug as fixed in release 5.16.0-0ubuntu1, but I *know* that is not true. As Daniel has pointed out, the underlying issue is that Unity draws itself above all other windows in X11. Unless this behavior is changed--and it was not in 5.16.0-0ubuntu1--Unity will always be visible over full-screen apps--as it always has been.

Not that it really matters; Unity is one of the things that drove me away from Ubuntu and I no longer use either. It seems Unity drove so many users away Canonical finally had to give it up. I am not surprised.

I do hope it doesn't mean the end for (Ayatana) Compiz. Ubuntu's fork of compiz is still much lighter and more advanced than compiz-core, despite the lack of flashy plugins.
