I have followed these instructions and find the behaviour is the same: If I try to to scroll when Chrome has focus, the page barely moves and 'bounces' back to the top. If I click away from Chrome, scrolling works as expected

Does this reproduce in an incognito window? Do you have any extensions installed?

Yes, reproduces in incognito window, also under new account. I have several extensions installed, but have previously tried disabling them all.

Some background:

I think I have been seeing this for at least 6 months. I concluded it was crappy old MS2000 Desktop and Mouse Combo, possible physical issue with the mouse (although it felt like a software issue). So treated myself to MS 3000 Combo. Same issues. Didn't explore further as hated 3000 Combo for other reasons, so switched camps to stupid expensive Logitech 710 Combo.  It's lovely, but looks like I think I am Commander of the Starship Enterprise, which is not a look I am seeking to cultivate. Also: Same issues.

I do not see this on any other machines, running the same setup essentially. This machine has two vid cards and three monitors. I have yet to notice the same behaviour in any other browser or application. 

If Chrome has focus: If a site has content bigger than my window depth, it matters not whether I wait for full page load or not - attempting to scroll down will succeed - a bit - then the page pings back to the top. Once it's loaded, I might be able to scroll down, if I really thrash the wheel. I also see a behaviour occasionally, where scrolling down seems to be working, then I am suddenly pinged back to top.

If Chrome doesn't have focus: Everything works just fine.

As clear as that - I can click in Chrome, see the behaviour... click outside Chrome, behaviour gone. Until I have to click something and then FERCHRISSAKES FORGOT TO DROP THE FOCUS time.

Fix it... please, please. I have been toying with the nonsense that is carrying bookmarks over to Edge so I don't have to live with this sanity threatening behaviour, but uugh...Edge...

We are unable to reproduce  the issue on the reported chrome version 61.0.3163.100 and on the latest dev 64.0.3263.0 using Windows10, Ubuntu 14.04 and Mac 10.12.6 with the below mentioned steps.
1. Launched chrome browser
2. Navigated to a web page
3. Scrolled with out any focus
We observed the scrolling is working fine.
Note: We performed the above mentioned steps on a single monitor setup. 

@Reporter: As per your comment #5 could you please verify whether the same behaviour is seen on any other browser or application and please check on a single monitor setup and let us know the behavior. 

Thanks! 

I have switched this setup to using a single browser on one monitor, one video card: Same issue.  The only other application I have seen the same problem with is Whatsapp Desktop for Win - which I suspect uses Chrome behind the scenes. All other browsers are fine.

Hi terferger@, could you follow the instructions here and attach a trace to this bug: https://www.chromium.org/developers/how-tos/submitting-a-performance-bug

Do it once with chrome unfocused and scroll working correctly, and again with chrome focused and scroll not working (ideal, capturing the scroll-to-top behavior you mentioned). Attach both traces here. That *might* help us find the cause.

Couldn't capture the 'bounce to top' effect - it's pretty rare. In both cases I had to dismiss a pane at the top of the trace containing 'MousewheelMousewheelMousewheelMousewheelMousewheelMousewheel....' before I could see the Save button.

Do you have any of the Logitech SetPoint software installed? I know that it use to do things sending special events to the Chrome window.

From the traces it appears that you have some extensions installed that are like taking up 50ms frequently. When you tried disabling the extensions did you reload the page? If you don't reload the page then the extension code is still run.

I do have setpoint installed now - but didn't with the previous two MS keyboard / mouse combos.  And yes, I have disabled all extensions and started a new Chrome session - same result.

We certainly can't reproduce the issue you are seeing. I guess a few things you could try are uninstalling the setpoint software. Quit Chrome completely then open a new incognito tab and load the page you are having issues with and then start tracing and perform the action.

Still waiting for a feedback. A screen capture would also be helpful.

Unfortunately, without a repro or any more details, this isn't very actionable. I'm going to close this - feel free to add information you think might help us reproduce or narrow down the cause and we can consider reopening the issue.
