Unity and my Gtx 660ti......are having issues
With some strange form of tearing/glitching it happens only along the top 1/4 of the screen and only when moving windowed things around in Unity...now it doesnt start out doing this but it always ends up happening, and its more than a bit annoying.....oh and I'm using the 3.10 Bianary driver

Hm – that's weird. I have the 660m and no such problems (I also have the 310.14 proprietary driver).
What settings have you set (in the "NVidia X Server Settings" tool - you can find that by typing "nvidia" in the Dash). Perhaps we can find out what's different between our systems and possibly solve your problem.

NVIDIA Settings -> OpenGL Settings -> Sync to VBlank enabled?

That was my first thought - I already tried to enable it on my machine to see if I can reproduce the problem. But I didn't get the above described tearing problems from enabling that.

Sync to VBlank's job is to get rid of tearing.... ;-)

I understand. But as I said - I don't get tearing either way with a related card (the mobile variant).

Tried a few differemt DE's (Unity 2D,LXDE, Xfce,KDE, and even E17) and this issue only happend in Unity 3D in 12.04...so maybe there is a bug in compiz or something

I think I'll stick with KDE....it seems to have better performace anyway, and the general layout feels more like home....thanks for the help tho guys

It may be specific to 12.04 I have a GTX660 using 12.10 same driver and no such issue.

Really? I had problems getting the official drivers to work with 12.10, some issue with the kernel headers.....

I had an issue very similar to this for a long time. Only about the top 10% of the screen was tearing though.

Here's what I did to fix it:
1. Update to the Linux 3.5 kernel if you're not already on it (if you recently downloaded Ubuntu, you should already have it)
2. Update to post-release-updates or newer graphics driver (if you have version 310, you've already done this)
3. Turn on both Sync to VBlank and Allow Flipping in your OpenGL settings.
4. If you're using Compiz, download ccsm (sudo apt-get install ccsm) and make sure the refresh rate in Compiz's settings agrees with that of your monitor. (In ccsm, go to Composite, then uncheck Detect Refresh Rate, manually enter the correct refresh rate below, then [Optional] check the "undirect fullscreen windows" box. Also, under the OpenGL section in ccsm, check the sync to Vblank box

If you've already done these things, it's possible your monitor's refresh rate isn't being detected properly. If that is the case, can you please post the output of this command:
xrandr
