Sounds like VRAM corruption. Does the problem persist between restarts (by which I mean shutdown, wait 10 seconds or so and then boot)? Also, you might want to try removing power to your external display and the same for your MBP (both AC and remove the battery) and see if the problem persists. Also, reset PRAM…
As a last thing I would try booting off a clean installed copy of Mac OS X, preferrably installed on an external drive.
Otherwise, call AppleCare.
Exactly the same problem has developed recently on my Macbook Pro. The computer has to be pretty hot before it starts, so I only see it after some heavy usage. Interestingly, my yellow cubes appear to be angled in a mirror image of yours. I can take screen shots of the effect and send them to anyone at Apple who cares to take a look. The effect disappears temporarily if I switch screen resolutions; but it returns pretty quickly. Did you manage to resolve the issue and if so, what did you do? My MBP's under warranty so I may send it back for repair as it looks to me like a typical VRAM problem.
MBP Mac OS X (10.4.9)
Forgot to mention that I ran the hardware test and it reported back that all is well.
Also, if you get the same problem after booting off another hard drive, it has to be a hardware fault!
i've been having this problem for a wile on my mac, but wasn't too often so i never worried too much about it but ever since i've upgraded to the new Leopard this problem got even worst, now happens all the time, i don't even have to do much to trigger.
have a look at the screenshots:
can someone help me?
