Never seen that. I've used nVidia cards for many years now with SketchUp. (Tried ATI once, but had too many issues.) I run multiple windows for the entire day.
Have you ensured your drivers are up to date?
Is your computer getting enough cooling? It's not overheating?
It's a rack-mounted machine in a chilled room, and it's fans are working properly, as is the one on the video card itself. The machines I use from my desk are all in a rack that's in the room next door (to eliminate their noise and heat). I've got a long DVI cable bringing the video to my desk.
That and the problem doesn't come back for quite a while if both mail and su8 are quit and reloaded. Were it heat-related it would come back much faster, if not immediately.
It is hard to replicate in that it involves letting the machine 'sit there'. The machine is not configured to use any sleep or power-reduction modes, so that's not it either. The drivers are current nvidia-supplied drivers (not MS nor card vendor). I've had the same problem crop up on a different machine, also using an nvidia card, su8 and mail.
It's not like I'm losing data, it's just a visual disruption, one that requires stopping work and reloading. Not a terrible burden on today's machinery, just inconvenient.
I'm sure there's a combination of factors coming into play here. I'm looking to find if others have seen the problem and possibly found solutions.
