Videos flick in Kubuntu. I have tried the different options in the 'Compositor Settings for Desktop Effects' Tearing Prevention and none seem to make a difference other than that if I put it on automatic, the top half of the screen flickers, and with 'full screen repaints' the whole screen flickers.
This occurs with nouveau, the Nvidia driver (352) downloaded from their website, and the one from software centre. I had the same problem while using Linux Mint Mate, but not while using the Cinnamon Desktop, or Ubuntu Unity Desktop.

While I've been watching videos online, they haven't flickered, but they have had tears in them.
