Unable to reproduce the issue on Win-10 using chrome reported version #64.0.3282.119 and latest canary #66.0.3335.5.

Attached a screen cast for reference.

Following are the steps followed to reproduce the issue.
------------
1. Set Win-10 scaling to 175%
2. Navigated to url: https://www.cnet.com/news/ and at 100% zoom did not observe any horizontal scrollbar.
3. When zoom is increased to 110%, a horizontal scrollbar is observed at the bottom of the page.

Also unable to repro. It's possible the site fixed the issue. billdillensrevenge@, you can also try clearing flags in chrome://flags and use a fresh profile as mentioned above. 

Here's some more information. I have no extensions, I reset all flags, and the issue remains when I try it in an incognito window too. The device is a Surface Laptop, the displays resolution is 2256 x 1504, but at 175% system scaling its effective resolution is 1290 x 860 (I went to this site to get that number https://www.whatismyscreenresolution.com) . I cleared history and went to the site again and the issue remains. I think the 175% system scaling is part of the problem, similar to  bug 777095

@szager: Could you please confirm whether this issue is similar to that of https://bugs.chromium.org/p/chromium/issues/detail?id=777095.

Thanks!

Yes, it's most likely the same, or a related issue.  Without a repro, though, it's impossible to know for certain.

Is there any way I can further help?

here is more information about my device that might be useful in reproducing this issue: when I go to https://www.jeffersonscher.com/res/resolution.php this is what I see

A very easy way to reproduce this issue: set Windows 10 system scaling to 175%, go to https://www.cnet.com/news/ (leave Chrome's page zoom at 100%) make sure the Chrome window is not maximized and slowly resize the width of the window, observe the scrollbar at the bottom appearing and disappearing as you do. I've attached a screenshot of what this looks like

I can't reproduce this in Linux, but then again, Linux has no such thing as system scale, so I tested with Chrome scale at 175%, which the instructions here in the bug report kind of seem to indicate is not the same thing.

do you have access to a Windows 10 machine?

Only a VirtualBox with no development environment and really low resolution.

Able to reproduce this issue on Win-10 and Ubuntu 17.10 using chrome latest stable #65.0.3325.146 and latest canary #67.0.3365.0. Issue is not seen in OS-Mac.
This is a non-regression issue as it is observed from M60 old builds. 

Hence, marking it as untriaged to get more inputs from dev team.

Thanks...!!

I'm pretty sure I narrowed down the problem: when I disable the "zoom for device scale factor" flag, I no longer see the horizontal scrollbar on https://www.cnet.com/news/ 

(search "Use Blink's zoom for device scale factor" in flags)

Can someone please look into this as it should be easier to track down the issue now? :)

I'm now seeing this issue on Google Images in the past week. I only see the horizontal scroll bar at 100% page zoom, when I go to 110%, 125% or anything lower than 100%, there's no horizontal scroll bar. Also, Firefox and Edge don't have this issue, so it has to be Chrome. Same laptop as I was using in the original post. v70.0.3538.77 

Screenshot attached, notice horizontal scrollbar

Oh and for Google Images, when I disable 'zoom for DSF', I don't see the horizontal scroll bar at 100% page zoom, but I DO see it at 80% page zoom. Kinda strange

I can reproduce this in Linux - 72.0.3602.2 (Official Build) dev (64-bit) - both with legacy layout and LayoutNG.

@ comment 21, can you repro on both Cnet News and Google Images as well?

Only when I google for cats. I don't see any horizontal scrollbar at Cnet News.

I guess that means they are different but very similar bugs
