--- Comment #8 from TestSubject sirbubbles01@gmail.com 2012-08-16 11:02:04 CDT --- After setting compiz to not decorate wine, I still have the Unity title bar showing on top of fullscreen wine games. Ie, I will fire up steam, launch a game, and the title bar will show on top of the game, forcing the wine virtual desktop into a slightly smaller fullscreen window, thus reducing the effective size of the wine window.
