This is affecting many webpages with long scrollable contents as observed in the duped  Issue 611294 .

Issue is seen on Linux Ubuntu 14.04, chrome version: 52.0.2733.0 as well.

Issue appears resolved in  52.0.2734.0 (Windows 10 x64).

Thanks for filing.  Verified this on my Linux release build synced to r392683.  Just go to www.google.com, search for anything, and scroll down with the mouse wheel.

I tried reverting my r392679 locally, but that didn't fix the problem.  I then went through other candidates in the regression range and found that r392652 is the culprit.  Reverting that locally fixes this.

Assigning to wangxianzhu@.  This does look pretty severe.

Comment 7 by alex...@chromium.org, May 12 2016 

Ah, it appears this is the same as  issue 611046  and already fixed.
