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?

Unable to reproduce the issue on reported chrome version 68.0.3440.84 and on latest chrome version #70.0.3515.0 using Ubuntu 17.10 by following below steps. Steps: --------- 1.Launched the chrome. 2.Signed in into google hangouts 3.Made a video chat request and clicked on share screen, able to see the screen got shared. Attached screencast and screenshot for reference. @Reporter: Could you please review the attached screen-cast and confirm if anything being missed here and request you to retry this issue with fresh profile without any extensions/apps or reset all the flags and let us know if issue still persists. Note:As the screen shared was not captured in screencast hence providing screenshot of it. Thanks.!

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. For more details visit https://www.chromium.org/issue-tracking/autotriage - Your friendly Sheriffbot

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 411b6d4e-ca7d8d80 b7d3b6c2-3f4a17df 3e006338-3f4a17df 2b6ab552-ca7d8d80 66df3e9d-607070a4 ebeb14fc-3f4a17df b7e2524c-1181467f cc20827f-ca7d8d80 3095aa95-3f4a17df 7c1bc906-f55a7974 9def365c-ca7d8d80 47e5d3db-3d47f4f4 125b7f68-898170a5 d442dfb7-ca7d8d80 9ca1387e-3f4a17df 1149accc-5c943877 4dc30737-b8a5ea08 a582a1b8-ad75ce17 121ae2bc-70ea8f25 aa011017-70ea8f25 edbcf7c5-a59393c7 5485fc4d-ca7d8d80 43f62d3b-20131bcc 3a0563a1-13b68faf 6a82868d-3f4a17df 9e5c75f1-8aa2c126 6872f671-991e1e1 e0ae5ae5-70ea8f25 2b86fd96-ae2f69dc d1cd70a5-70ea8f25 4ea303a6-85fb2903 6e6e0c7e-3f17a7d8 d92562a9-4d2fac87 4da5ae82-91c810ef 2a32876a-70ea8f25 5586049f-a18a14e4 757a5d98-70ea8f25 4bc337ce-7b60a216 1354da85-f1a864dc 494d8760-52325d43 3ac60855-486e2a9c f296190c-8282a32d 4442aae2-6bdfffe7 ed1d377-e1cc0f14 75f0f0a0-d7f6b13c e2b18481-cdc3d902 e7e71889-4ad60575 b1ceb06f-d1372334 618c533-70ea8f25 41aa6aaa-da82a76f 94e68624-803f8fc4 6204e469-ca7d8d80 8866fe4f-ca7d8d80 81c6897f-e872b86f ea0f933d-29e3c6de
