GTX 1060 + CentOS 6.7/6.8 - awful tearing + unable to watch anything from youtube

With this config and NVIDIA drivers 370.28:

Section "Device"
        Identifier      "Videocard0"
        Driver          "nvidia"
        BoardName       "NVIDIA Corporation GP106 [GeForce GTX 1060 6GB] (rev a1)"

I get awful tearing and I’m unable to watch any videos from YouTube because roughly 30% of frames get dropped in full screen both in Firefox + Adobe Flash and Google Chrome + native VP9.

Please fix ASAP.
