I interested to play Spiral Knights game in Ubuntu, this game support fullscreen playing, however the game return windowed after closing. So, I should reconfigure the game to be in fullscreen every time before playing. It was annoying, and it happen in Natty with Unity Session. So, I think it was related to compiz. After looking hours for what compiz plugin that cause the fullscreen game to be windowed, I found that compiz workaround plugin -> legacy fullscreen support was not enabled by default. So I enabled it and the game can now to start in fullscreen.

The same thing happened to me a while ago when I tried to play Trine. Checking legacy fullscreen support fixed the problem. It would be great for newbies if this option was checked by default.
