I am facing some serious web page rendering issues with Chrome.
It is more prominent during javascript based animations and stuff on websites like youtube.
I have tried removing chrome using (sudo apt-get purge google-chrome-stable) and then reinstalling it. But the problems still persist.
The same webpages work correctly on firefox on ubuntu and chrome on windows. The problem only shows up when I use chrome on ubuntu.

I think the issue has started after I updated to the latest version of Chrome. I have used Chrome previously on this machine without any problems.

I have attached a image that demonstrates the issue.

What could possibly be the problem?

PS: here's the output of lshw -c video:
