I have a similar problem with my Trident 8900, except it not only
occured in windows. I get small random lines appearing when I'm 
doing a lot of work with the mouse. I noticed it at 600x480x16 and
 800x600x16. I haven't tried any higher resolutions yet. I have tried
 many VGA games and do not get the same effect, except for a VGA Trek game.
I didn't even get it with my gif viewers at 1024x768x256!

As for fixes, well I'm going to talk to my dealer and then maybe
a FIRM phone call to MICROSOFT.
