    Wondering if anyone else has ever seen this on a late 2012..
    Pictures reduced by 50% to keep them manageable. - Zoom in to the screenshot of TombRaider to see the fun green dots.

    really fun graphic glitches.:( :confused:

    Anyone heard of this?

    I had the same problem, called Apple and the sent a tech to my home, replaced, firstly the screen, when that didn't work out, they called again the next day and replaced the graphics card.
    All sorted and no issues any more.
