This is very bad. Essentially, embedded client is useless with this. I hope somebody from zoom can comment on it and explain. ---

We also experience this issue since at least version 1.7.7 (included - we did not test with previous versions unfortunately) - We can reproduce this error 100% of the time by using a high CPU spec chrome box for the host. - We never reproduce this error with a low CPU spec chrome box for the host. - The video stream works no matter the bug appear, thus look lilke a **UI bug, and a race condition one**. I did not inspect the code but would definitely give a try to @darragh.duffy last comment about async / await depending on what you found during that troubleshooting session. This is also a critical issue for our business. ---

Hi Folks, I can say that the Zoom engineers reached out to me. In fairness to them then spent a lot of time with me on Friday last looking at the issue. I now believe they have a solution, I tested a version yesterday 1.7.9.x and it passed all my tests. Thanks again to the Zoom Engineers to taking the time to run through the issue. -Darragh. ---

This is good news. I’ve had pretty bad results getting consistent or any information on the Web SDK. Do you happen to know for exactly which version a fix was provided? Is it the CDN hosted 1.7.9 and the “secret” (not documented anywhere I could find except in a buried forum thread) 1.7.9.1 for doing development testing? Thank you! ---

Hi All, The Zoom engineers provided a “beta” version for me to test. They will provide a production version as soon as possible. I am also waiting for this production version, and currently I am running 1.7.7 in our production environment. I can say that the “beta” version 1.7.9.X fixed the issue during tests. I have not taken this beta version and applied to our production. ---

We confirm that 1.7.10 fixed the black screen error we got when hosting meeting with high CPU spec chrome boxes. At least before this release we could reproduce 100% of time the issue, now after multiple tests we could not reproduce it. Thanks for the update ! ---
