Teams only show 4 streams at a time on Linux, the video/audio quality is mediocre and the video quality in the webclient is worse than the one using an Electron container, probably to force the app. Screensharing always tends to get stuck after a while, and they ignore any requests to start supporting Wayland, even while it takes minimal changes(update Electron).

Nowadays it's easy to setup your own conference server, and use webbased clients that don't require yet another Electron container. For instance, Galene(https://github.com/jech/galene) is an excellent resource-friendly SFU built on top of Pion(Golang).

Shameless plug: I'm the author of Pyrite(https://github.com/garage44/pyrite), an alternative WebRTC frontend for Galene
