    Booted up my Macbook Pro this morning and I noticed this strange yellow-speckled discoloration at the top of my desktop screen. I'll attach a screenshot--its in the center of the screen, right below the top menu bar. What is this? Ran a complete cycle of Onyx, but it's still there.

    Yes, it's still present after switching the desktop background. Strange :confused:

    seems to be getting worse...moving windows and dragging the mouse across the screen creates more of them.

    That's really weird. I don't think that it is a hardware issue, because if it was a hardware issue, I don't think that we would be able to see it on the screenshots?

    Interesting, I hope you have AppleCare. :D

    ack, no, I dont have Applecare at the moment...

    I tried creating a new user account, but problem persisted. Occurs with folders as well as web browsers. Running Onyx didn't help either.

    restarted and its back to only being on the top, without following dragged folders and such. very strange... Sorry for so many screen shots, but I've attached another of the yellow part when pressing F11

    That looks like bad video RAM to me. Try booting from a Mac OS X install disc and see if the problem happens there. If so, it's definitely hardware.

    Maybe try an archive and install at this point. Before that you could try running the diagnostics from the install discs that came with your mac too.
