Update 8/10/21A few updates now have made the pinwheel subside quite a bit, hope that future updates will make it go away for good.Previous:I constantly get the pinwheel when switching between programs I.E. Explorer, Outlook, Teams, amazon music, notes, etc. These are not high power requirement applications. It is especially bad when docking and undocking from my workstation.  I have my previous MacBook Pro setup exactly like this model and it powers through without issues. The problem has gotten so bad that I have momentarily switched back to my previous one until Apple gets the software figured out with some updates. Disappointing!
