A recent buggy update to Radeon graphics drivers breaks Chimera. However, if you get the very newest driver it fixes the problem. It is in Radeon Software Adrenalin 21.4.1 from 20 April 2021. The Windows display driver is version 27.20.21002.112.

Dear Chimera Users
My name is Sergio Garay, I have installed chimera-1.15-win64.exe on Windows 10pro 64bit. But when the program starts to run, the system gives me the following error message and the program closes:

chimera exited abnormally; the exit code was: -1073731819.
use the -- debug command line option for the full error message

I tried installing the two previous versions of the program, with the same result.
My PC has a Radeon RX 580 series videocard, and the system uses a WDDM 2.7 video controller.

Could you give me any advice on how to fix this problem?
Sincerely
