I'm running 10.6.1 on a MBP, NVIDIA GeForce 9600M GT with 256MB of
Vram and QC 4.0(103.1). The error usually kicks in after about 30
minutes. I'll simplify the QC comp a bit and send it out to you.
Thanks again for the hand,

Mighty QC List, I have a visualization that accumulates multiple
words over time, and the once the comp has been running for a while
it starts to draw words that are corrupted into strange blocks.
In the image notice that some of the word sprites are drawn as
distorted blocks or lines although the original string is feeding
into the sprite intact. Any hunches on this?

Are you on 10.5 or 10.6? Which GPU are you using? What kind of
uptime does it take for this to set in ("a while" could equal a few
seconds or a few days)? Can you post the composition (or one like
it that reproduces the issue)?
If you're on 10.6, give it a spin on 10.5 -- the drivers on 10.5
seem much more reliable (in my completely unscientific opinion and
limited hardware experience -- just a GMA950 and an NVidia 8800), so
it could be GL drivers to blame. It could be QC4 to blame (or QC3,
if you're on 10.5). It could be bad vram (in which case it's
specific to just that machine -- however, I'd imagine bad vram would
manifest itself elsewhere as well ;)
