Same issue for me, running MS Teams on a Macbook Pro (16-inch, 2019), and everything was working fine until a few weeks now, I would say it started mid-december. Video is laggy or in slow motion. Never had this problem for years using MS Teams on Mac. Probably a bug with the latest update. Hope MS will fix this soon, it's very annoying. I don't have any lag when using any other app using the webcam (Zoom, Google Meet).

I also had this issue on my Intel Mac Pro 2019. It seems solved after I did the following:

Close Teams. In Finder navigate to <home folder>/Library/Application Support/Microsoft/Teams and clear out all the folders with Cache. I don't know which one solved it, but I just removed all contents of all folders with Cache in the name. It now is not stuttering anymore.

Pietert1905 Problem has been fixed with the latest version released in March (1.6.00.7354). From the MS Teams : "The product team has developed an update which is expected to be part of an update to the Teams client expect in early March which should address the issue which was related to a change to enable dynamic composition where we skip the composing of a frame if there are no changes. For Mac we need to lock the CVPixelBuffer that represents the composited frame. There was an issue where we were potentially missing the unlocking of a locked pixel buffer before we presented it to display. This resulted in the visual artifacts."

Problem is indeed fixed for me, no more video lag!
