Gnome-Shell top panel over fullscreen games

Question

I've been using gnome-shell for the last two months, and I realised that whenever I try to run games like psychonauts or trine2 in fullscreen, the shell's top panel is still visible.

The strange thing is, that does not happen with video players like gnome-mplayer or vlc, or with flash videos (e.g. from youtube).

I'm running Ubuntu 12.10 and Gnome-Shell 3.4.1

Many thanks!

I've been trying to figure this out as well, and so far the only work around I've found is that you can get rid of the top panel by minimizing any open windows in the background. For instances if you have a web browser open, then start a full screen game like trine2 or minecraft, minimize the browser, then start it.

It should get rid of the top panel.
