Video blanks when switch focus to chat or meeting
There is a similar issue open on feedback
Teams meeting causes monitors to go black · Community (microsoft.com)
I would vote up on this, or raise a new issue on feedback if this isn't specifically what you are experiencing. Once done I would open a support ticket referencing the feedback item along with screenshots and OS versions
I could suggest a few things such as updating the Teams client and ensuring all the devices are on the latest version, and clearing the cache of all the devices - and you may want to run through this, but seeing that it occurred suddenly, and its happening in both the web and desktop client experience and to multiple users would suggest its a bug, or something is occurring on Microsoft's end. They will be able to run through all with you, but gathering the above data can shorten the interaction with support.
Thanks for raising, and hope Microsoft resolve it. Once you open a ticket drop the ticket number here and I will raise to Microsoft engineering this end. No guarantees of a response but I can get it in front of them.
Best, Chris
For others that may have this issue.
Since posting this appears that the windows version of web teams has been fixed. Unfortunately MacOS is still not working properly.
We have isolated the cause of the issue down to use of back ground effects. If this is enabled then switching focus, or simply disabling and then re-enabling the video, you will be met with a black screen.
To rapidly reproduce.
1. go to calendar
2. select Meet Now, start meeting
3. settings, back ground effects, and turn those off and apply
4. Toggle video on/off and you will get a image
5. Settings background effects - select any other option and apply
6. Return and toggle video - you get a black screen upon re-enabling video.
This impacts user privacy of teams on intel and Apple Silicon Macs on MacOS12.3 and 12.4 that I have tried. To maintain video easily in a conference you need to disable the background effects, or switch to chat, which makes the video window small, then click the small window to maximize it again to get the video back.
Hope that assists any one else with the similar issue.
Safari does not have the options to have back ground blurring.
Mozilla has an open 2+yr old ticket with Microsoft for support of video with teams. However, if you add the 'Fix Teams Video Extension' to firefox and then configure the custom user agent string to be the same as the current Edge for Mac then the video in teams meetings works even with back grounds enabled. The current work around appear to be use firefox.
- Just an update that while video outgoing works with firefox it does not have incoming video. All other chromium browsers suffer the same issue. I guess either turn off privacy or switch conferencing services is the solution.
BradSP65 Unfortunately the behaviour of Teams Web app on a Mac has changed today for the worst. Now if you have backgrounds enabled you can not minimize and maximize the video window to get outgoing video to not be black. As of today this does not work and attempts to get the video to function results in Teams now stating that it can not work with the camera and removes all video attempts altogether and disables the camera. The only way to make Teams web now work is to disable all backgrounds removing your privacy. Time to update the ticket.
- Since there are now other mac users on mac forums reporting the same issue with the PWA I'll see if there is interest there in looking at the javascript code with teams web and see if anyone can identify the exact problem. As it is 100% reproducible on any Mac using teams web and Edge I suspect with the right skilled person that it should be easily identified.
