Comment 1 for bug 1591260

I had fixed this under 14.04, but the upgrade to 16.04 brought back the tearing (and other reboot problems).

The following fixed the tearing:

1. remove compiz
2. install compton
3. in Session/Startup, make sure compton is loaded with the following:

   compton --backend glx --paint-on-overlay --vsync opengl-swc

You probably need to make sure that VSync is enabled in the nvidia settings as well.

Logout and then back in.
