Guix doesn't actually package AMDGPU as far as I know, you have to use The Forbidden Channel if you have an AMD card and want to actually use it. But also yes, it's super buggy for me as well, sometimes it freezes, sometimes it just glitches out. Also IMHO this further proves my point that we need a "safe graphics mode" boot option, see issue 54945.
