Does this only reproduce on specific sites? I tested on a Nexus 5x running OMR1 and wasn't able to reproduce, so it's not clear what percent of the time this bug reproduces.

Our resizing background should be white, so I'd expect to see a white gutter if we aren't resizing the page properly. I believe the web contents use black to fill in extra space, so if we resizing the web contents viewport but not the webpage, I'd expect black. Grey is unexpected, unless Samsung devices don't use the window background for resizing. Perhaps the page itself has a grey background that's being drawn.

Lowering to P3 given that it requires a combination of force enable zoom and multi-window mode and the website is still functional. If this bug is confirmed, it should move from Unconfirmed to Available.

It reproduces always on the below webpage.

This page itself has grey background. Issue reproduces only when force zoom is enabled.
I'm not sure about other sites.

Note: This issue is not observed if "Force enable zoom" us not enabled.

Sorry for the spam comment #10, had to update due to the network issue.

Thanks!

Unless we can repro on more than this one individual site, I think this is another web site issue (not Chrome).

Just to update more info:
Issue is also observed on economictimes.indiatimes.com(noticeable grey patch can be seen)  and mobile.nytimes.com (minor grey patch is observed).

Attached the new screen cast here:
go/chrome-androidlogs/833799 >> 833799-nytime&economictimes.mp4

Thanks!

Thanks for checking! I'll try to do some debugging as time allows to make sure we're sending the right viewport size from the Java layer to the renderer.
