The annoying part is, I was performing a whole night long on this bug, and read at 5am, that issue is likely fixed with 180.29! Now I'm waiting for the binary repo. At least I've learned a few things about Nvidia's config mechanism. I'd be pretty much interested in the result you get running a plain "<code>nvidia-xconfig --no-composite</code>" only, on your plasma. In think tearing should be completely gone this way.

The tearing was still there, although not as bad. Mine is hooked via DVI to HDMI onto a Panasonic Plasma display. The video doesn't skip, so the tearing is obviously the effect of the refresh rates/V-sync. I have a feeling it may be worse on the plasma because it's natural refresh rate is so high (most are in the 450Hz range). My setup is also a little weird. I have two X servers running, one for my desktop and another for the TV screen. I commented out the Composite option last night, but did not explicitly disable it. Also, even with it commented out, compiz-fusion still ran on the desktop screen, so I don't think it was fully disabled. I didn't think about using the nvidia-settings tools to play around with the refresh rates though. I'm going to mess around with it tonight and play around with my xorg.conf. Thanks for all the suggestions. It's a good starting point to try tweeking things around. Hopefully the new release may fix these issues. I upgraded to the .27 drivers in the Gentoo tree last night.
