Can we confirm that this bug is still in the beta version?

I noticed that the same problem also occurs on Chrome Canary for Android on a Google Pixel.

The exact version with the issue is: 71.0.3562.0 (Official Build) canary (32-bit), Android 9; Pixel Build/PPR2.180905.006

On Chrome Stable (69.0.3497.100 (Official Build) (32-bit), Android 9; Pixel Build/PPR2.180905.006) it works just fine.

I have attached screen recordings from the two browsers.

Is there anything I can do to help speed up the process of resolving this bug? I am worried that Chrome 70 is nearing its release date while the issue remains.

Apart from Chrome OS, I have witnessed the same visual glitch on the following Android configurations, starting with Chrome 70:

Cannot reproduce on 71.0.3578.99 on Pixel 3 and Mac. Is this still happening? Thanks!

I can no longer see the problem on any of my devices. You can close this issue now, thank you.
