Which Desktop environment are you using?
I had the same problem with my HTPC and xbmc. I used Gnome for a while now. I read in the xbmc forums disabling composite would solve the tearing.
So I disabled the composite extension in xorg.conf and changed the XSession in lightdm to xbmc. TADA! Tearing is gone 
But Gnome, I think, requires the composite extension.
I am currently getting rid of Gnome on my desktop PC. I will switch to xfce, which doesn't require the composite extension. I had also tearing on the desktop PC on Gnome with mplayer.

the problem exists in 346 driver...
a simple workaround is to set vsync to none and back to when is poor in kwin desktop effects...but this is not really a solution..
i am running 3.18 kernel kde gentoo64 |

I can confirm that the problem persists on nvidia-drivers-346.35, but its not the ***only problem***:
https://bugs.gentoo.org/attachment.cgi?id=397514&action=edit
So be careful with the updates meanwhile. Meanwhile I cannot test test much as I'm using xorg-x11 opengl as a workaround to bug#541372.
