I'm running 1.4.00.8872 on a M1 Powerbook and still have the annoying covering the whole screen thing. It happens when I start the application, but also when switching accounts (which still is a pain in teams on Mac, contrary to the iOS version that let's you sign in to multiple accounts simultaneously)
Currently on 1.4.00.7175 (older than your version) and the issue is fixed for me. Also, Apple hasn't sold a Powerbook for years. I guess you're meaning an M1 Macbook, which is also what I'm using.
