Videos are pausing/jerky/stuttering as is general overall operation, sound is fine

Reported by bretad...@gmail.com, Apr 10 2018 
UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.66 Safari/537.36

Example URL:
All, especially Youtube

Steps to reproduce the problem:
1. Launch, watch videos or scroll through a long page, nothing is smooth
2. 
3. 

What is the expected behavior?
Smooth, as per prior versions

What went wrong?
These are after Chrome Beta updates on my various systems on Ubuntu Linux 17.10 and 18.04 Beta 2.  All was fine 2 weeks ago.  

Did this work before? Yes Not sure of the number...

Is it a problem with Flash or HTML5? HTML5

Does this work in other browsers? Yes

Chrome version: 66.0.3359.66  Channel: n/a
OS Version: Ubuntu 17.10 and 18.04
Flash Version: 

Contents of chrome://gpu: 
See attached file (it's too long)

Oddly, opening the Chromium task menu (shift esc) resolves the problem completely.  Closing it resumes the problematic stuttering/jerky behavior.

Yes, issue 822549 sounds like the same.  The biggest things I would add are:

- On my system, Firefox is absolutely not impacted.  Only Chromium and Chrome.  I've even seen the first time use Chrome/Chromium animation freeze.
- It happened on my Ubuntu Budgie 17.10 system only last night after a Chrome update downloaded, but happened on my Ubuntu Budgie 18.04 system the week before, again after an update, both Chrome Beta, but again, non beta Chromium also impacted.
- Opening the Chrome/Chromium task window eliminates the problem, closing that window makes it return.   

Would it help if I screen capture videoed the problem?

Can you confirm if disabling hardware acceleration fixes the issue? If so I'll dupe this bug into the other one and let the GPU team provide guidance on the feedback needed.

Yes, disabling hardware acceleration fixes issue.
