As you can see they are some glitches in the game, glitches which I didn't have with the demo. I tried with the version of Adrenalin I had (the last one before the was released), also upgraded to 20.4.1, same issue.
There may be a problem with the driver. I suggest you share this forum link with AMD with that...https://www.amd.com/en/support/contact-email-form
