Two finger scroll momentum exceedingly high in 68.0.3440.106 (Official Build) (64-bit)

Reported by jsl...@gmail.com, Aug 28

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.79 Safari/537.36

Steps to reproduce the problem:
1. Update from 67.0.3396.79 to 68.0.3440.106
2. Use two finger scroll on any website
3. Page continues scrolling upon release of fingers for significantly longer than in 67.0.3396.79. 

What is the expected behavior?
The expected behavior, as it was in 67.0.3396.79, is that the scrolling should end quickly after the release of two fingers. Also, a two finger scroll flick should be able to traverse an entire webpage from top to bottom. 

What went wrong?
In 68.0.3440.106, the scrolling action has significantly more momentum and takes much longer to come to a halt. Additionally, the scrolling rate is substantially slower than in 67.0.3396.79. Multiple two finger scroll flicks are required to traverse the page. 

Did this work before? Yes 67.0.3396.79

Chrome version: 68.0.3440.106  Channel: n/a
OS Version: 10.0
Flash Version: Shockwave Flash 30.0 r0

Hi Viswa,

Thanks for your reply. Looking at your attached video, I agree that there is no difference in scrolling behavior between v68.0.3440.106 and v67.0.3396.79 on your system. It seems that the behavior in both v68 and v67 on your system is the 'high scroll momentum' behavior I refer to in the first post. 

On my system, I am still experiencing the same difference in behavior between the two versions. On v67, the scroll momentum is much lower and flicking allows me to traverse an entire webpage from top to bottom. The scrolling behavior is similar as to when I scroll in other programs, such as Windows explorer, etc. 
On the other hand, in v68 there is very high scroll momentum and flicking does not traverse very far down the webpage. 

I would like to retain the behavior that I experience in v67 (and all earlier versions) with the lower scroll momentum and high scroll speed. I was wondering how I may diagnose the difference in scrolling behavior between v67 and v68 and how I can implement the behavior desired behavior in v68.

Thanks very much!
