I knew this was a problem, but my MBP JUST started showing it, as the attached pic shows. i was like OMFG NO! and sleeped it to get some food, and now its perfectly fine. I Know i have the worst monitor, but all seemed fine so far, until this. And it only happened for about 5 minutes... So, i didnt read too into this when it was a hot topic, but what does it mean?
