I have a Mac and have downloaded the game. The one issue I have is that whenever I start up the game, I get this glitchy looking screen. The game itself runs perfectly fine, but the screen is glitchy; even when I start a New Game. I'm not sure why it's doing that. I've tried the V3 and V4 ones and got the same result. Is anyone else with the Mac version having this problem? Is there a way to fix it?
