Ok, it seems on some of my screensavers, that there is a clear line which scrolls from the bottom of the screen to the top of the screen. Now this only seems to be happening on the screensavers which are constantly moving fast, (such as the Flurry one that comes with Tiger), the ones which just zoom in and out of different pictures do not seem to be affected. The clear line is seen as it distorts the moving/swirling image as it moves up the screen. Its a bit hard to describe but has anyone encountered anything like that? This happens multiple times a minute, and while it doesn't seem to be causing a problem, it is quite annoying.
