My 2011 15" MBP (16 GB Ram, 750GB HD, and 15-inch (1680 x 1050) display) has for the last month begun to show randmom distortions. Please look closely at the menu bar. This can happen anywhere on the screen, in any application. Sometimes it is on a webpage. Sometimes in Pages. Sometimes, it's in Finder.
What causes this? What can I do to address it?
iPhone 5, iOS 6
I could not get it to stop switching graphic modes. I'd change it, then it'd switch back on its own.
As if Apple's RAM isn't third party...
Good luck,

I received my MBP back from Apple. They replaced the logic board and display. I now have a new issue. When they graphics card uses the Radeon 6750 i get this blue hue to the whole screen. If I use the app you recommended it will allow me to switch to integrated card which removes the blue hue. Anyone have ideas?

John,
It's a bug that a handful of us have experienced - and it's not isolated to one model or the other. Whenever the discrete video card kicks in, there's a bluish tint to the screen. I had the problem, used Cody Krieger's gfxCardStatus to isolate the problem, and after a few weeks my problem just 'went away'. Some have reported luck by turning of automatic graphics switching. I don't know what the real solution is, but you shouldn't have to live with it long - I hope: I didn't and I've no idea what 'solved' the problem at all.

I have this problem with my MBP's 6750M. It makes the machine unusable because the whole graphics system can freeze and require a restart after only a few minutes of use.
Since this started happening, I have been launching into my Lion partition most of the time. The problem has not shown itself in Lion for me; only in Mountain Lion.
I also suspected the dedicated GPU. Will try it with the GPU disabled. If that works, I would be curious to know the source of the problem -- is there a bad kext in ML? or does Lion just not use the dedicated GPU much?
Why is my Macbook Pro Screen displaying random distortion?
