Hi, thank you for reporting a bug to us.
Could you describe specific scenario (exactly what is the application, what is the web address and what did you do) or attach the Android screen recordings?

To record the screen as a movie I use command
adb shell screenrecord /sdcard/movie.mp4

It is various applications where you can either click a "see more" button e.g. Facebook mobile website on Chrome Beta Ver: 56.0.2924.23 or Wikipedia Beta Ver: 2.4.184-beta-2016-12-14(also other versions previous to yesterdays update), an example of how it affects Wikipedia is attached.

timav@, I tried to reproduce this issue on webview: 56.0.2924.23 on HTC ONE/X9/M and LG V20/N no luck. 

Not sure this issue is device specific? 

I was unable to reproduce it as well on the same device as reported, HTC 10, Android 6.0.1, same Wikipedia Beta and WebView 56.0.2924.24

Dheenu, can you give it a one more shot with HTC 10 and close if still not repro?

My device is a Samsung Note 5.
The steps to reproduce on my device are to follow a link which opens in another tab.  Use the back button to navigate to the source page.  Scrolling then causes the page to snap back repeatedly towards the link which has highlights around it.

From the reports, I don't think it's device specific? Could be a random bug depending on the scenarios? But I've seen it in Chrome Bet and Wikipedia Beta no matter the article or version number. It's mostly contained in apps that use Android WebView (as far as I'm aware anyway)

Again no luck as per the steps 

Note:-
But with Accessibility ON, I'm seeing the scrolling issues (same as the video attached in comment#2 )

HTC 10/MMB29M
webview: 56.0.2924.23

Please bisect with Accessibility ON.

 Issue 674943  has been merged into this issue.

Main site I am seeing this on is www.hardocp.com
Using Chrome beta for Android.
Application I've run into this bug on is Amazon version 8.9.3.200

Just turned Lastpass and Tasker accessibility off and I don't have the problem. 

timav@, 

Here is exact step to repro this issue.

Precondition:
Turn Accessibility > ON

Steps:-
1. Install and launch wikipedia beta
2. Search Google Chrome (select the Google Chrome - Web broswer develped by Google)
3. Now Select "Chrome OS" and Double tap to open the page > You will see Read Article pop screen. Now press the back button > You will be on Google Chrome Page.
3. Now scroll up and down.

You will see this issue

Here is bisect range on M56/webview, (M55 I'm not seeing this issue)
Good: 56.0.2909.0
Bad: 56.0.2910.0

Here is bisect range
https://chromium.googlesource.com/chromium/src/+log/56.0.2909.0..56.0.2910.0?pretty=fuller&n=10000

Marking regression tag

Removing the owner for the next bug cop to pick up.

You are looking for a change made after 430005(GOOD), but before 430006(BAD).

Broken on Chrome and webview on same CL#  

Assigning to the author of potential offender CL https://codereview.chromium.org/2465403003 according to #16.

This is a duplicate that should now be fixed.

Verified on latest M56 webview on HTC 10 and LG/G5- Looks like this issue is fixed.
