Hi all! When one of our late 2011 MBPs (top spec BTO) switches automatically to dedicated graphics there's noticeable corruption of text and blacks go green in places. Firefox is the primary browser, but it happens in Safari too, and the corruption can be seen in About My Mac. Sounds like the dedicated graphics are faulty, no? This'd mean a full logic board replacement from Apple? I'm thinking of using gfxCardStatus to force integrated-only graphics until I can get the machine away to be fixed - sound like a plan? Such a shame; a really high end machine, has probably been faulty since day one, the user just didn't notice.
