Whenever I choose to open a game from the app store in full screen mode with my macbook pro retina (selected solution: 1440x900) the games are not displayed correctly and seem oversized ... the only thing i can do is open the game in "windowed" mode and then switch to fullscreen mode which is pretty annoying if you have to do it every single time ... is this a known issue with Mountain Lion? I dont think this has ever happened to me before with Lion ...
