After receiving a call using a bluetooth headset (Boss QC-35II) typing on a bluetooth keyboard (apple) becomes incredibly laggy. This continues even after the call has ended. Closing teams restores the keyboard to its prior behaviour. This may correlate that teams appears to use very large amounts of CPU after this happens.
This behaviour does not appear to happen when using teams in google chrome, I also do not have it when any other audio is playing.
I would use chrome permanently but I miss the desktop notifications.
