Screen flickering

Reported by salehboz...@gmail.com, Jul 8 2016

Issue description

Steps to reproduce the problem:
1. The screen keeps flickering while using Chrome! especially on Facebook - Imgur - Twitter
2. 
3. 

What is the expected behavior?

What went wrong?
I think it's a gpu issue! After I disable hardware acceleration the problem disappears, but the browser gets slow.

Suspecting linux graphics driver issue.

Do you still have this issue with the latest stable Chrome version (57)?
Yes, but it seems that the flickering has been reduced!

Can you record a video showing the flickering? Or provide more information about it? Like, is it only the Chrome window that flickers or the whole desktop? You're using Ubuntu with Unity as before, correct?

Actually this is a known issue and is being investigated.
Yes, the chrome window is the only one that's flickering.
