I'm getting strange graphics corruption occasionally on one or both of my monitors where the graphics get all corrupted. I wish I could take a screen capture but every time I do, the capture comes out perfect despite the graphics/windows/text being jumbled in a blocky mess. (Updated with a photo of the screen)
This only started happening after I updated to 10.6.7. If I reboot I might be fine for 10 minutes or an hour but it eventually comes back and almost certainly if I play multiple videos (eg. 2 or more) in Quicktime on the same monitor at once.
My GPU config consists of...
2x Nvidia GT120 each driving a single 24" LCD ACD via MDP
In googling this issue, I found out there is a known issue with Nvidia drivers with 10.6.7 not supporting Quadro cards...

That's not my problem, but it is Nvidia driver related, indicating they changed the drivers in 10.6.7. Other's with 320M are complaining of slightly different issues...

I'm wondering if anyone here with Nvidia cards and 10.6.7 has noticed anything?
UPDATE: I took a chance and installed the NVIDIA drivers mentioned in the Apple KB article here. After some very preliminary testing, I can't seem to recreate the problem.
If this ends up fixing this problem and this is not unique to me I'll be pretty disappointed with Apple's QA process.
