So I'm running Kubuntu 15.10, and I'm having problems with screen tearing.
Currently I'm using Chrome as I want to be able to use Netflix, but the problem persists in other browsers too, I don't think it's a Chrome specific issue.
The graphics driver I'm using is the proprietary one (fglrx-updates) for an AMD HD7870. The driver seems fine, I noticed a great performance increase when I selected it with window effects etc. And it's running my screen at 144Hz completely fine.
Anyway, as the title suggests, I'm quite frequently getting laggy screen tearing in videos. Not only does this occur in videos, but sometimes even in pictures (until I refresh) and even when scrolling. It's usually diagonal tearing from bottom left to top right, but not always. Sometimes there's a lot of it.
It doesn't always happen, but does probably 60-70% of the time. It seems to get worse when I have multiple tabs open etc.
I was looking up online for solutions and many people said it could be the compositor, but I couldn't find any fixes that work with the current version of KDE/plasma. I added an exception for firefox and chrome to something for the compositor but I think that was only for fullscreen video, when the problem I'm getting is not only just fullscreen videos, but videos in general and even pictures and text when scrolling (and it didn't seem to work anyway).
Any help at all would be greatly appreciated.
Cheers :)

OK so I just tried out Netflix, and I get screen tearing when it's not fullscreen but not any once it's been fullscreen for a couple of seconds. So I guess it must be the compositor? How can I exclude a whole browser from the compositor?
