    Has anyone noticed this while they were scrolling in Firefox? It makes the browser look really ugly with these weird lines on the side.. Is there a way to get rid of it or is this ANOTHER bug in Lion? It goes away as soon as I scroll up.

    Doesn't happen to me. What version of FF are you using?

    It's most likely GPU related and not application specific. The graphics end in Lion is buggy.

    It's a bug in the graphics engine of Firefox, but also partially a bug in Lion. See, every window in Lion has this rounded edge. Firefox using GPU likely picks up a square, disregard the round edge, and push the page up when you try to scroll down. The end result is that there is nothing to display there, and then it draws that weird black "pad" thing. But it re-renders itself occasionally when the CPU is used instead of the GPU, thus correcting the problem.

    I'd think a beta version of Firefox should fix that bug.

    Thanks guys. I found out that it had something to do with me using Firefox 3.6 upgraded and the black lines went away. :rolleyes:
