Google hangouts only shares screen if all experiments disabled

Reported by khym.cha...@gmail.com, Aug 3

Issue description

UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.84 Safari/537.36

Example URL:
https://hangouts.google.com/

Steps to reproduce the problem:
1. Go to Google Hangouts
2. Start a video chat with someone
3. Try to share the screen.

What is the expected behavior?
The share screen button is there and works when pressed.

What went wrong?
The share screen button is NOT there normally.  It only appears when chrome is started with "--no-experiments".

Did this work before? N/A 

Is it a problem with Flash or HTML5? HTML5

Does this work in other browsers? Yes

I tried disabling experiments in groups to narrow down which experiment causes the problem, but the problem persisted no matter which experiments I disabled.

Works fine with chrome beta (68.0.3440.75) and chrome unstable (69.0.3497.23)

You seem to be doing everything right.

Some additional info:
* If I have all experiments turned off the "share screen" button appears when initiating a video chat even before I invite anyone.
* If experiments are on then the "chat" button is also missing from the menu.
* If experiments are on then when initiating a chat, before having invited anyone, both the "You are the only one here" and the "invite people" button are missing from the video chat window.
* The JavaScript console for the video chat window shows no problems, but the console for the main Hangouts tab shows some errors loading from ssl.gstatic.com and 1.client-channel.google.com

Attached are screenshots of the video chat window top bar and menu when it's working (files starting with "good-"), a screenshot of the video menu when things aren't working (file starting with "bad-") and the JavaScript log showing the loading errors.

Thank you for providing more feedback. Adding the requester to the cc list.

I tried disabling the experiments out of blink CORS (chrome://flags/#out-of-blink-cors) and QUIC (chrome://flags/#enable-quic).  This got rid of all the errors in the JavaScript log I attached previously, but didn't fix the problem, so those errors aren't relevant.

No longer able to reproduce with 70.0.3538.110.  Can the experiments automatically turned on via variations change over time?  If so, maybe the experiment which caused the bug used to be turned on via variations, but no longer is.  If not, then the bug must be gone.

Current variations, as reported by chrome://version
