    Hello everyone,

    I have a problem recently, about two days now. Every time I open up photoshop, my screen starts to get glitchy and pixelated. It gets worse and worse when I move around on my screen. But when I close down photoshop, every time works fines. I have attached screenshots of how bad it is. Sometimes it gets worse than the screenshots.

    I have the latest operating system as well.

    I tried downloading older versions of photoshop, and the problem still happens. I tried an smc and pram reset just to see if it works but it did not help.

    Can anyone provide me with some help on what I should do?

    Thank you.

    Get it to Apple. Looks like discrete GPU failing. Unfortunately a common fault of 2011 MBP's with discrete GPU. Photoshop forces discrete GPU. I hope you have applecare.
