I have a similar experience on 10.0RC2 with Radeon HD 8570.

- boot works ok and radeon driver detects the card and creates 
radeondrmkmsfb0 properly

- startx (modular-xorg with no config file) starts with radeon driver 
and work, glxgears -info work and report AMD as renderer and vendor
	glxgears -info:
	GL_RENDERER   = AMD OLAND (DRM 2.50.0, 10.0_RC2, LLVM 13.0.1)
	GL_VERSION    = 4.5 (Compatibility Profile) Mesa 21.3.9
	GL_VENDOR     = AMD

- starting any application requiring DRI messes up the screen completely 
or just the application window. The same with starting picom or enabling 
a compositing in xfce4.

- adding a gpu.conf file in /etc/X11/xorg.conf.d forcing the 
"modesetting" driver gets me software rendering but at least everything 
works - albeit very slow:
	/etc/X11/xorg.conf.d/gpu.conf:
	Section "Device"
		Identifier "radeonhd"
		Driver "modesetting"
		BusID "PCI:6:0:0"
	EndSection


	GL_RENDERER   = llvmpipe (LLVM 13.0.1, 256 bits)
	GL_VERSION    = 4.5 (Compatibility Profile) Mesa 21.3.9
	GL_VENDOR     = Mesa/X.org

- recompiling the kernel with "radeon" driver commented out and enabling 
"amdgpu" doesn't bring drm up during boot and no drmkmsfb is enabled.

A Radeon HD 7450 is on my way for further tests. Then I'll move towards 
Radeon HD 6000 series.
