Teams on Mac video is instantly choppy

Same issue here as well, and it is now impacting our day to day business. We had a call with a Microsoft engineer, and we were able to determine that Mac call quality issues began on 12/20, and have been rising ever since. Roughly 7% of all calls involving Macs are now having poor call quality, to the point where the meetings/calls are unmanageable.

Can someone from Microsoft please dig deeper on this?

This has been happening to me as well since mid-Dec on my MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports) running macOS Monterey 12.6. Teams version is 1.5.00.33356. Yes I have an external USB camera (logitec) and the jitter / phantom re-appearing key frame issue happens on the second monitor.

This makes Teams for videoconferencing unusable and I hope it gets fixed very soon. Videoconferencing in-browser does solve the video glitching however even that has become completely unstable for some reason and I get bounced out of meetings after a few minutes. I've had to convert meetings over to Google Hangouts or Zoom as a result, and seeing how those all work perfectly fine (as did Teams prior to mid-Dec) leads me to believe that this is a 100% Teams issue.

I could be totally wrong, but this does look like a key/i frame (delayed) retransmission issue. I don't see any pixelation so delta frames are working as they should but it's like the next time an i-frame should be displayed on a second monitor, Teams is picking one out of the buffer that is the previous one and not the current. Another thing to note is that this is only affecting the display of all videos and my camera feed, but to all other participants my video seems normal.

Same issue with Teams version 1.5.00.33356.

Same issue here with an Intel 16-inch, 2019 MacBook Pro. Since 12 December laggy and annoying. OS is Ventura version 13.1 (22C65). Downgrading helped for a second, auto update made sure my day was ruined again. I'm hosting a lot of meetings including training sessions, and the lag is driving me insane.

Just piling on here, but I'm experiencing the exact same issue since 'upgrading' to 1.5.00.33356 on an iMac running OS 12.6 (21G115) w/Radeon Pro 580 8 GB GPU

It's becoming incredibly frustrating as it's the primary videoconferencing solution for our enterprise.

As many others have stated, I also couldn't find a 'trusted' source for downloading version 1.5.00.31156, so open to any recs on a clean source to resolve these issues.
