...hope this bit of info would help, tearing is more on the horizontal sync functionality, try to findout the horizontal range setting in your xorg.conf and compare it with your display specs, edit xorg.conf if necessary. (or perhaps this may be a display software issue)

This worked for me.

Go to System > Preferences > ATI Catalyst Control Center (Administrative)

When it opens, go to More Settings under 3D.
Then under "Wait for Vertical Refresh" move slider to Always On.

And don't worry, the screen will flicker some, but then it should fix screen tearing issues. It did for me.

Hope I helped.

Huh, so far, everytime you restart, you have to turn it off, then turn it on, just for it to work again. After I restarted after figuring this out, it started screen tearing again, with the option on. I went and turned it off and apply and it still screen teared. So i turned it on again, and it stopped screen tearing.
