We recently (finally) upgraded from 2019 to 2020.  I've noticed that the quality of the shadows where they meet the model are poor (pixelated, with a white boundary):

This is in a fairly powerful desktop workstation with a Quadro P4000 but I also see the same behaviour with a laptop running totally different hardware.  I don't recall this happening in previous versions of SolidWorks.  Has something changed with 2020?  Perhaps a new setting that I'm just not aware of?

Thanks,
