I installed glmark2, as it seems to give more information :

Let me know how can i give you more information.
I am still looking for information or solutions.

BTW, When I am using Mozilla Firefox 56.0 it works
when I am using Chromium 62.0.3202.75 Built on Ubuntu , running on Ubuntu 16.04
or google-chrome-stable, it does not work, getting the same error (Nov  5
14:23:31 PITA kernel: [  335.832424] [drm] stuck on render ring
Nov  5 14:23:31 PITA kernel: [  335.833016] [drm] GPU HANG: ecode
8:0:0x85dfbeff, in chromium [1745], reason: Ring hung, action: reset
