STRANGE SCREEN VIEW IN GALLERY

I have never had trouble with how Zoom has displayed on Win11,  Today the Speaker view is perfect.  At that point the gallery view...little squares running across the top...is fine.  However, in Gallery View results in a very strange display...a vertical line of  about 5 distorted and truncated rectangles.  Impossible to tell if it is multiple rectangles of same participant or different participants.  Only top half of each is shown and it is very distorted.  HELP

If this is the wrong board to post this, please let me know.
