Glitchy graphics in OSX, possible GPU problem? MBP 15" 2011

[mbiddle01]

Hello

I currently have glitched out, colourful, checkerboard style graphics being rendered in various places in OSX, most noticeably in the desktop wallpaper, when I press "space" to preview an image in a Finder window, and on top of regular window graphics, like over the top of my IRC client for example.

Recently the shadows around windows have been glitching out too which is probably related.

Is it obvious what the problem is based on the screenshots? It started off subtly with just small patches of squares and slowly got worse over time, so now I have examples like the wallpaper image where it fills a lot of the screen. This suggests to me that maybe my GPU is dying, but maybe it's something else.

Any ideas?

Thanks

Definitely looks to be the GPU, You'll need to have the logic board replaced. If you have applecare call apple for some warranty work
