Glitching mac graphics

Hello Jaws123987,

Thanks for that info and for choosing the Apple Support Communities. If I understand correctly, you are having graphics issues when you try to play games from the App Store on your MacBook Pro. You can figure out if unexpected behavior is related to a user file or setting by trying to reproduce the issue from another user account. This process includes creating a new user account, logging in to it, and testing for the issue.

I am experiencing this exact issue. However, this is occurring with 90% of the games I try whether they are from the App Store, Steam or elsewhere. The only game that works reliably with no issue is World of Warcraft.

I have tried with another user account and had the same result. However, if I try in safe mode, the game will load but it is in a different resolution and is not able to be adjusted rendering the game(s) unusable. With multiple Command+Tab presses, I am able to sometimes get the game graphics to load properly. This is the exception to the rule however.
