私は大学講師をしております。

ブレイクアウトルームを使用し、１５０名程度の講座で、一組３名、計５０組に振り分け「すべてのルームを開く」ボタンを押すのですが、そのボタンを押した以降、ブレイクアウトルームが作動しなくいことが２回続いています。
ブレイクアウトルームの設定は何度も確認しておりますが、特に問題が見当たりません。
生徒同士が交流でき、意見交換できるグループワークを中心とした講座展開を大切にしているため、大変困っており、原因などがわかる方がいましたら、ぜひ教えていただきたく思います。

Recently Zoom started flickering, more often when used in fullscreen and when someone is sharing their screen. 

I'm using linux PopOs and the flatpak version of Zoom. I've also tried the .dev version and had the same problem.

Grad if someone could help me.

As many have reported it's not possible to share applications or screen with zoom version 5.9.6 and later until 5.10.7.

I and probably many others would like to use Wayland as it is default in Gnome.

The last working version that I found to be working is 5.9.3.1911 version (https://zoom.us/client/5.9.3.1911/zoom_x86_64.rpm). 

Does anyone have 5.9.4 or 5.9.5 Fedora version or least knows last 4 numbers of the version so we could download and test?

or the workaround to use X11

Another option to disable security and be able to share screen within Wayland is to:

ALT+F2

lg

#and enter in the console

global.context.unsafe_mode=true

This will give an option to share screen, but many times it will be shared just the background

Presumably it will be working from the versions of 5.11 on

Any additional feedback?

I was hosting a Hybrid meeting using two Android Smartphones running Iriun webcam and the host Windows 11 laptop with Iriun webcam version 2.7.1

The host Iriun program was initiated and the two "cameras" connected and were test selected, everything OK. I then joined the Zoom meeting from the invitation circulated and was made co-host, the laptop webcam worked as normal but when either of the two Iriun cameras was selected, the screen flashed between a barely visible image and the looking for camera display.  Neither camera image would hold and I had to abandon the Zoom meeting. I then turned the android phones off and restarted them, rebooted Iriun, turned off the laptop restarted it, restarted Iriun connected the phones which displayed within the Iriun window. Restarted Zoom,  reopened the meeting, selected a Iriun camera and the same result, no image, just an alternating flash between a split second display and looking for camera.

I had run a test the previous day without having any problem from the same venue which has fibre to the user broadband and very fast WiFi.

I have run a test today from a different venue with fibre to the cabinet broadband, also with no problem.

Has anybody any idea what causes this sort of glitch and how it can be prevented?
