Hi George,
	What driver do you have installed exactly?  A recent driver update for Radeon cards breaks Chimera but it was our understanding that the very latest update (Radeon Software Adrenalin 21.4.1 from 20 April 2021; Windows display driver version 27.20.21002.112) fixes the problem.

I have the latest driver installed on my graphics card (amd radeon 5600 xt) and have tried installing both the latest windows 64 bit release, and the daily build (may 20 2021).
