Recently (maybe forever) I have been having some problems with quicktime videos. If the video consists of fast-moving high-contrast graphics, horizontal glitches appear. It's like it is having trouble refreshing the screen, however, these glitches still appear on a CRT connected to the powerbook. I have tested the same videos on a tower, and they are fine. The only other graphics problems I have are when I open very large (12000x9000 px, for example) images in quicktime and the brushed metal quicktime border doesn't render correctly. Other than that, the graphics are fine. Is this a problem with my graphics card? Does anyone else have these issues?

I have experience very similar problems. It's like a white flicking "noise" quite visibly apparent on some of the Apple supplied screensavers.

I've also seen it on the desktop once or twice where it disappears when you move a window there.

Does anyone think this could be a graphics card related issue? All other graphics operations seem to be fine, but I can't think of what else it could be due to. Does anyone not have any problems with high-contrast, graphics heavy and fast motion quicktime files?

According to a tech I spoke to at Apple, the white noise on the photo-based screensavers is a known issue for which they have not yet found a fix.
