regis.caspar@  Thanks for the issue.

Tested this issue on Ubuntu 17.10 and Windows 10 on the reported version 68.0.3409.2 and the latest Canary 68.0.3414.0 and unable to reproduce the issue.

1. Launched Chrome and navigated to the given link above.
2. On scrolling through the page, cannot observe any clipping on the page.
Attached is the screen cast for reference.

Request you to retry the issue on a new chrome profile without any flags/extensions and update the thread with the observations.

Thanks..

Hi, thanks for your answer.

First test: guest session.
--------------------------

Was able to reproduce on BBC's twitter account (guest.png and demo.mp4). Inspecting the dom the elements are there and even well detected by the inspector. When hovering some content appear. (I used a tweet with 500+ answers)

The only flag I have "ON" that is not standard is "strict site isolation"

Will try again with the flag reset to it's default.

Second test: guest session.
---------------------------

Using a new Ubuntu user, I did start Chrome, and tried again to reproduce (see attachment) using the BBC tweet. I still see the issue (no flag, no extension besides the gnome-shell one, new chrome profile)

I hope that helps.

Hi Chris, I don't understand this bug merge. I did report 825280 and you did fix it (I was able to verify it was fixed), but there's some new similar issue or some regression in the dev version..

Ok, re-opening.

As per comment #3 & #7, as this issue is not reproducible at TE end, removing 'Needs-Bisect' label and requesting chrishtr@ to look into the issue and help in further triaging.

Thanks..
