Touchpad scrolling with double finger on long page is slow then "catches up"

Reported by craigwha...@gmail.com, Apr 25 2017

Issue description

UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.133 Safari/537.36

Steps to reproduce the problem:
1. Load a large page
2. Try to scroll from the top down the page
3.

What is the expected behavior?
Scroll normally. Scrolling in firefox works fine.

What went wrong?
The page doesn't scroll as expected in other applications. The only way I can explain it is - Think of the scenario where a car is spinning it's wheels on a slippery service but then gets friction and starts to move. This will happen constantly over and over during the actual scroll motion. I find scrolling in pages with less graphics (chrome bug page for example) scrolls slightly better. I've tried turning smooth scrolling on through chrome://flags but it hasn't made a difference.

Output from xinput:

I've searched for the following open/closed bugs:

https://bugs.chromium.org/p/chromium/issues/detail?id=427230 - I don't think this is the same issue as this.
https://bugs.chromium.org/p/chromium/issues/detail?id=593453 - Seems like there are a lot of issues on this one bug and some people have started separate bugs for their separate issues.

Did this work before? N/A 

Chrome version: 57.0.2987.133  Channel: n/a

Tested on Chrome Stable #59.0.3071.115 & Dev #61.0.3159.5 on Ubuntu 14.04 and able to reproduce the issue. 

This is a non-regression issue and able to reproduce from M-47 #47.0.2499.0. Marking it as untriaged so that issue gets addressed.

Observations: 
1. Scroll behavior seems to be same on FireFox as well. Screencast link for reference: https://drive.google.com/a/google.com/file/d/0B91MtOa4hcAbbHh2a0ZpZ3YtMms/view?usp=sharing
2. Scrolling with mouse seems to better.

Thanks.
