Display tearing is a gpu/gpu ram/ram problem.

If you are using onboard video have to tried to increase the amount of 
reserved ram? 

Do you have an external card? Maybe it can be replace or perhaps it's 
overheating and is in need of a cleaning.

Also, do you have enough swap space, if you don't have a lot of ram, that can 
affect things as well.

Just things to explore.

Hope this helps,
