I've been experiencing major screen glitches on my gigahertz PowerBook ... in the past, mostly related to using the dual display feature of the laptop (either with S-Video or the DVI output). For example, playing a DivX movie on S-Video out, and working on the LCD at the same time, will cause these glitches. Another easy way to reproduce is by plugging in an external monitor to the DVI out and running one of the zoom-and-pan screensavers like Photo, Cosmos, Beach... on both monitors.

Now after experiencing glitches in these situations, its been 'spreading'. Just today with no external monitor hooked up my internal LCD is starting to develop these glitches just while web browsing.

What do these glitches look like, you ask? If you can imagine a VCR tape with bad tracking... here's some pictures I snapped the other night:

Has anyone else seen this issue????

YES. I experienced the same strange graphic glitches 2 days ago. i'm hoping it has to do with safari and nothing with the os. I too was minding my own business surfing the web when the graphics started tweaking out on me. I quit safari but noticed that the glitches spread to my os! i was freaking out because i though something real bad was going on but when i restarted it went away. it did happen one other time after that and restarting fixed it. as of now it has only happened twice, but WHY it happened i have no clue.

so youre not the only one
