I tried running Ubuntu on nVidia Titan Black Edition, AMD R7 240x card, and built in Intel 3000/4000, all of them had some sort of v-sync problem with lots screen tearing in browsers and/or video players.
Anyone knows what's the underlying problem of this? I've seen many people complain about tearing in Ubuntu when I googled this issue.
Is screen tearing a challenging issue with Linux platforms in general? I mean, do you guys face similar problems but learned to live with it? Or you don't mind screen tearing? Or it's just my luck that all of the video cards I tried somehow have tearing issues under Ubuntu?
Edit: here is a tearing test video to see whether or not your system has tearing related issues http://www.youtube.com/watch?v=5xkNy9gfKOg
My Ubuntu 14.04 shows severe tearing in chrome and slight tearing in firefox with this test.
