I had all sorts of problems with CS6 and Lion on my MacbookPro Quad i7 w/16gb ram. Everything from flashing white frames from Speedgrade renders, to scaled clips shaking, 422HQ clips created in aftereffects rendering out just as a green frame, to clips rendering out what looked like an opacity wipe on half of it, to kernel crashes and on and on. I spent a lot of time scratching my head. Many issues I couldn't find any posts about anywhere.

I upgraded to Mountain Lion and haven't experienced the crashes and the last few renders seemed to be without issues, and can use the OpenCL hardware acceleration, so far, but still take a long time on pretty straightforward sequences having only some scaled video, some text.

Regarding your glitching, whenever I scaled something, had keys or mattes I'm using, I render out at "maximum render quality' and if I have the time, maximum depth, then go somewhere for a long while. Even though I'd have the previews set for 422HQ, I stopped using those for export. Sometimes I still have to go back and crop or put a matte on the scaled items because I'll get these vibrating edges. Don't know if that's of any help since you're on Snow Leopard but, for what it's worth, I have had much more stability with CS6 after ML upgrade.

To resolve the green frame issue, I just ended up rendering out new files out of Aftereffects of the problem clips as a 422 instead of 422HQ and at least was able to get it to render video instead of green panel. Haven't the foggiest why.
