I am currently using elementary OS Freya with my Lenovo G510. It has a 4th generation Intel Core i3, with Intel HD graphics. I was searching for some answers regarding the screen tearing I am experiencing with Freya. I found a solution from this forum and they provide solution by editing the /etc/environment file and insert this line of text CLUTTER_PAINT=disable-clipped-redraws:disable-culling.
I was wondering if there is no harm on my system if I will tried it? Or is there any other way to solve the tearing issue?
