      I have enabled "EXAVSync" and it does work fine.

        Nouevau doesn't have the precise vBlank in NV50 up to NVC0 and newer. Maarten Lankhorst from Canonical made a patch for that but it turned out that while it resolved problems on XMir it also halved the FPS on X server.
        I take back that X server doesn't have tearing problems on my PC running Unity in Ubuntu 13.10 with Nouveau drivers. I've tried running some tearing tests on YouTube as verde suggested and I definitely see tearing in those two videos:

          I hope XMir is not pushed into Ubuntu 14.04 LTS. It should be added on 14.10.
          Just let the option to use it in Ubuntu 14.04, but not the default.

            Mir should be added (if they still want to go Mir, I mean) in 14.10. XMir should never be used as a mean to run a desktop.

              I think that they moved on and they will now work only on XMir for single programs. There was a new blueprint on Launchpad titled: Rootless X on Mir.

              IMHO it's much better to focus for them on Mir and develop XMir as rootless X for the purpose of running legacy programs.
