Well it fails for me. I've included a screencast too. I have the Hangouts extension already installed and I'm already signed in to Google Chrome but when I start the extension it asks me to sign in and presents me a blank page.

@ I coudn't reproduce the issue as well. 

Linux 69.0.3497.23 HP Z440 desktop version. OS: Debian Rodete. 

I think there's a good chance this is the same bug as crbug.com/875020. I'm going to hold off duping these bugs because 875020 is restricted, just FYI for folks who may work on this.

Sorry I don't have permissions to view that link...

Retried to reproduce the issue on Windows 10 and Ubuntu 17.10 and unable to reproduce the issue by using Hangouts extension(version 2018.515.419.1).
As per comments #2 and #6, as this issue is not reproduced at TE end, CC'ing kkaluri@ from RVG Issue 875020 for further action on this issue and adding 'TE-NeedsTriageFromHYD' label.

Thanks..

adefaria@gmail.com, can you post your about:gpu info here? To do this, type about:gpu in the url bar, then click the "copy all" button, then paste the result here.

Stephen, can you track the tracking down of this on our side?

I can nag people. Scheduling seems the most likely cause, but maybe it's something else.

I shouldn't own it until it is confirmed and reproduced. I track it anyway because it remains Unconfirmed and Blink>Paint is a component.

Still we are unable to reproduce the issue on debian Rodate using chrome reported version-69.0.3497.23 & latest beta-69.0.3497.42 as per steps in C#0 & video in C#3 & mentioned the same in C#2,6 & 11.

Tried different cases:
--------------------
Case 1. Launch chrome, install extension & click on hangouts extension , click on sign in button & able to sign in successfully.
Case 2. Once user sign in to chrome browser , automatically google hangout extension also gets signed in (if extension is already added).
Case 3. If user is not signed in to chrome browser, then also user able to sign in google hangouts successfully without any issue(if extension is already added).

Hence removing Needs-Bisect & TE-NeedsTriageFromHYD labels for now. Please add if required.
Thanks..!

adefaria@gmail.com: you are using nouveour driver, which is not very stable. Chrome only allows it because those who install it usually are adventurous and know their way around.

Can you try running Chrome with --disable-gpu and see if the issue goes away? If yes, then likely it's a nouveour driver issue.

Nice try and I was hopeful but running with --disable-gpu doesn't change anything :-(

Assigning to Devlin for extension triage.

Well miracles of miracles - this morning Chrome wanted to be relaunched and wham, the extension now works. I did not capture the previous version but the new version is Version 69.0.3497.81 (Official Build) unknown (64-bit)

This looks like it's just a bug in the hangouts extension - it opens a window to https://hangouts.google.com/webchat/blank?undefined&pli=1, which is, in fact, a blank page.  So it doesn't look like it's a painting issue in Chrome, or something in the Chrome Extensions system.

jawag@, can you route this to the proper hangouts folks?

Issue 875020 has been merged into this issue.

The NextAction date has arrived: 2018-09-10

I've flagged this to the Hangouts team and they're taking a look.

Please do not miss my post which says that this is working fine for me now with Version 69.0.3497.81 of Chrome (Beta) and Version 2018.515.419.1 of the extension.

@adefaria Yep, thanks for making sure we saw it! :)

We're just making sure our bases are covered, since if you experienced this, there's a decent chance others have as well.  If it's already fixed for everyone, great! - but we should double-check just to make sure.

Unfortunately I am still seeing the issue with Chrome 71.0.3549.0 (windows / mac) and Hangouts 2018.515.419.1

There are definitely more people experiencing this
