For future reference, the version of Reddit krajshree@chromium.org visited was not the redesigned version. To view the redesign, you have to be signed in.

Despite this, I followed your instructions and found these results

The latest Canary doesn't have the issue.
Incognito mode also doesn't show any issues.
The scrolling was still inconsistent when I visited those sites again.
I disabled any extension that was affecting the display of a webpage (Stylish etc.) and the problem disappeared.

So I'll go ahead and say that there may still be some bugs with the scrolling with a touchpad, but none of these bugs are present in an unmodified version of Chrome.

Thank you for providing more feedback. Adding the requester to the cc list.
