I have a MCA M4. This has been the case for me for the past 2-3 months.

First I cant cut any whatsapp call without the rainbow circle thing spinning for 10-15 seconds.

Whenever I screen share my whole macbook hangs and sometimes i have to switch it off.

Also why is no one talking about how the desktop goes black when switching. I am SURE that this was not the case before Tahoe.
