Recently I noticed some distortions on images in Safari. I told myself it was just the Yosemite Beta. To do some testing I installed the gfxCardStatus app to switch back and forth between discrete and integrated graphics. When switching to discrete from integrated, the entire display turns to static and then seems to be fine. Does this mean my discrete graphics card is on its way out? And since it's soldered to the logic board am I looking at almost $900 to repair? I've got an appointment with the Genius Bar later this week, just curious what anybody else thought? After some research it looks like the 2011 MBP has had lots of problems with the graphics card.
