Bug Description

Test case:
install compiz-plugins-main 1:0.9.4+bzr20110527-0ubuntu1 in natty-proposed

                1) Compile and run the program attached in the bug report
                2) Click the toggle fullscreen button and it should unfullscreen
                3) Check if the fullscreened window appears in alt-tab (it should)

If you run an application under Unity that starts as fullscreen, you're stuck in fullscreen mode forever. The app can call gtk_window_unfullscreen() but it doesn't do any good -- unity on natty beta ignores it.

I'm attaching a simple C GTK test program that demonstrates the problem. Compile it as specified in the comment at the beginning, then run it with no arguments. It starts up in fullscreen mode. When you click "toggle fullscreen", it calls gtk_window_unfullscreen(). That works in gnome 2 on lucid and gnome 3 on natty, as well as several other window managers, but in unity the unfullscreen() does nothing.

You can also run the program with an argument of 0 if you want to test it starting up in normal non-fullscreen mode, then toggling into fullscreen, to see the difference in behavior.

Same bug happens with compiz + classic ubuntu (on natty), so this looks like a compiz bug...

Changing package to compiz. This bug also occurs under Gnome2 Classic under natty -- but not under the earlier gnome2 under lucid. Some folks I talked to suggested this was more likely a regression in natty's version of compiz, and not specific to unity.

Indeed it works now. But when I launched Firefox after having closed it in fullscreen, the Firefox window was restored with it's title bar underneath unity's top panel. So it looked like a maximized window without window controls (close/minimize/maximize).

I am also having this problem with firefox on first launch after shutting down with it fullscreen. This is a regression for me, it happened very recently. In order to use firefox properly again I must unmaximize, quit, and relaunch firefox.
