Tested the issue on windows 10 using chrome M61 #61.0.3163.100 and latest stable M62 #62.0.3202.75 and unable to reproduce the issue.

Tested in lenovo thinkpad laptop with touch pad.Attached screencast for reference.

@ bwat47-- Could you please check if you could reproduce the issue in latest stable in other machines with a clean profile without any extensions and flags enabled and update us with your observations.

Thanks!

Hi hdodda,

In order to re-create it you need to open the link in a new window (not a new tab). Here is a video example: https://youtu.be/5HOtL5_6PNU

Another way to re-create it is to go to chrome:flags, click the reset all to default button and then click the 're-launch' button. After the browser re-launches, if I try scrolling on the chrome:flags page it's really laggy.

Note: When this issue occurs, if I simply re-size the new window, it starts scrolling normally.



The only other laptop I have available to test is an old asus u52f. I do not see the issue on that machine, but that laptop does not have a precision touchpad. Also works fine on desktop machines with a mouse.


Also, I came across another bug where other users are describing the exact same behavior: https://bugs.chromium.org/p/chromium/issues/detail?id=713907

see comments 10-16

bwat47@ Thanks for the feedback.

Re-tested this issue again on Windows 7,10 and Mac OS 10.12.6 using the latest Canary 64.0.3256.0 and Stable 62.0.3202.75 and unable to reproduce this issue by following the below steps.

1. Launched Chrome and navigated to chrome://flags and reset all the flags to default.
2. Launched Chrome again and navigated to reddit.com
3. Right-clicked on any link eg. comment of one post and opened it in a new window.
4. Scrolled through the page and can observe no lag in scrolling.

Request you to please update chrome to the latest stable, retry the issue and update the thread with the observations.

Thanks...

Uninstalled chrome (and had it delete browsing data). Did a clean install of chrome stable 62.0.3202.75 and I was still able to re-create it

Also tried installing chrome canary  64.0.3256.0 and saw the same issue there

I can not reproduce on XPS with touchpad. Add block to 779372 reminder me to double check this issue.

Note: As a test I tried disabling hardware acceleration in chrome. With hardware acceleration disabled, I cannot re-produce.

I tried updating my intel drivers to the latest from dell's website (old drivers were version 21.x, new ones are 22.20.16.4771). After updating the drivers and rebooting I can still re-create the issue though (with hardware acceleration enabled)

I can reproduce by right click - open new window.

I suspect this is the same issue as  issue 713907 . Chao, if you agree you can just dup into that bug. IMO, since a window resize fixes it - this sounds like a bug on our end rather than missing the precision touch pad APIs.
