Slow scrolling

Reported by gier...@gmail.com, Dec 29 2017

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.108 Safari/537.36

Steps to reproduce the problem:
1. open www.repubblica.it 
2. scroll with touchpad
3. do the same with Chromium and is much faster with Chromium

What is the expected behavior?

What went wrong?
Scrolling a webpage with touchpad is really slow compared with the same build of Chromium installed on the same machine. This only happens in windows 10.0.14393 and only with Chrome. There's some wrong setting in Chrome i think.

Did this work before? No 

Chrome version: 63.0.3239.108  Channel: stable
OS Version: 10.0.14393.1944
Flash Version: Shockwave Flash 28.0 r0

I've updated to the latest drivers (video drivers included) and reinstalled windows. This only happens with Chrome, not with Chromium, and only with 10.0.14393 build of windows.

Unable to reproduce this issue on 63.0.3239.108 with windows 10.0.16299.125 and with 15063.786 with steps mentioned below.

1. Navigated to www.repubblica.it  in chrome 63.0.3239.108 and scrolled using touchpad.
2. Navigated to www.repubblica.it  in chromium 63.0.3239.108 and scrolled using touch pad and observed equal scroll rate.

As ET team doesn't have any device with 10.0.14393 version of windows, could someone from Inhouse team take a look into this issue.

Thanks!

I can confirm that the issue happens only with windows 10.0.14393!
the other version 1511 / 1703 and 1709 doesn't have the issue.

Just to clarify, the slow scroll happens with EVERY website...not just with the one i've mentioned.

thanks

This is likely not a setting in Chrome but a dampening of the events by the OS with executables with the name "chrome". We have confirmed with Microsoft that this shimming has been removed in later releases and we recommend you use the latest Windows 10 version.

thanks for your reply! well i'd like to stick with win 10 14393 LTSB...i'll try to report the problem to Microsoft

Comment 6 by gier...@gmail.com, Jan 6 2018

thanks to the comment2 i think i've found a workaround to make the scroll fast again: rename the chrome executable from chrome.exe to googlechrome.exe. I've tested and is back to normal but can this cause any issue in chrome?

Comment 7 by gier...@gmail.com, Jan 9 2018

Hi all,
can you explain why, if windows dampens the events of the executables name "chrome", that chromium which has a process and executable name chrome.exe (same as chrome) is working fine and not chrome? (have a look at my screenshot) 
In the screenshot you can see the google chrome exe is renamed by me though (to Ghrome.exe) that's my workaround to make the scroll work again.

thanks
