For a while now been getting these strange artefacts on my MBP (mid 2010) screen. Usually happens when I cmd + tab to another window. Most of the time it's yellow in color, however sometimes it's red/green/black. If I move the window or cmd + tab again it will go away. Also happens on external display through the MDP

Unfortunately, it probably indicates a video hardware problem. More than once, when I have started seeing video artifacts, hardware failure follows. – Thorgrim Feb 6 '13 at 21:47
Yea I'm still under applecare but cant really lose my machine for the 7 business days they want to fix it – dstarh Feb 7 '13 at 15:27
I've had good luck using a local Mac shop that can perform Applecare repairs. A couple of times they have confirmed the problem and ordered the parts. I brought the machine back when the parts arrived. In both cases the repair was 1-2 days not 7. Good luck. – Thorgrim Feb 7 '13 at 22:48
