Issue descriptionUserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2859.0 Safari/537.36 Steps to reproduce the problem: 1. Use a touchpad that supports two finger scrolling 2. Find a page that requires scrolling 3. Scroll What is the expected behavior? Scrolling should behave the same, or at least similar to other system applications. The page should move an amount that is consistent with other applications given the same amount of input. What went wrong? Scrolling is very slow, flick scroll gestures end almost immediately rather than inertial as expected. Did this work before? Yes Chrome version: 55.0.2859.0 Channel: dev OS Version: 10.0 Flash Version: Shockwave Flash 23.0 r0 I'm not sure what version this broke in, I am currently using the dev branch and have been using Edge as my primary browser for a while but scrolling worked fine prior to switching to Edge. In that time the Windows 10 Anniversary Update also shipped, so there may be changes that affect this.

Confirmed on a SurfaceBook pro. Flings in particular feel much worse than in Edge. I suspect that we just need to disable smooth scrolling for high precision trackpads. Yash, I recall some discussion about this before, is there an existing bug for this?

Issue 545234 has the prior discussion.

I did try disabling smooth scrolling via chrome://flags and it didn't seem any better, it still took significantly more input to get the page to scroll the same amount as other Win32 or UWP applications. Perhaps there's more behind the scenes but toggling the flag didn't do it for me.

Good point, I forgot to try with the flag disabled. It does indeed still feel bad with the flag disabled. Regular scrolling feels fine to me, the fling curve just needs to be a bit longer.

I'm finding non-fling scrolling to be slower as well. Here are two screen caps showing how much Chrome scrolls vs Edge using the same speed scroll motions. Chrome attached to this one, Edge to follow.

Sahel is most familar with fling at this point and will be doing some work related to it this quarter, probably makes most sense as owner for this. |
