    This is my first post on this forum and I need help.
    It appears 2 days ago.
    I'm on 10.3.9
    G4 1.2
    Trouble : stranges pixels (green/ yellow/ bleu) appear on my display especially when I'm using Safari or Firefox. It's look like a "checkerboard" (Damier in French) made in an horizontal line.
    I've try to : clean my ram but it still to be there after a restart.
    It doesn't seem to be an hardware problem as when I use Capture this manifestations still visible at the same place on the pict.
    It can be modify (Clean) when i change colours (million to thousand)as it deseapper. When i move an icone on the strange part of the screen it act as a gum.

    As i want to use my computer with millions colors I need help to find a way to solve this problem.
    Thanks in advance for your time and your help and excuse me for my bad english :)

    This might be due to a corruption in some kind of image cache... although it might also be a hardware issue, even though it goes away under certain circumstances. Try to download a utility like Onyx that can clean caches on your Mac (not always cleaned at restart) and see if this helps.
