There are four Vulkan driver options for AMD graphics chips at this

Original Vulkan driver produced by the Mesa team.

Newest Vulkan driver produced by Valve. Fedora 33 ships with
this. Try '/RADV_DEBUG=llvm' to use the older backend to see if it
fixes your visual bug./
* AMDVLK
Open source driver produced by AMD.
* AMDGPU-PRO
Closed source driver produced by AMD.
Ah, thanks. That clears it up. RADV_DEBUG=llvm, unfortunately, doesn't clear
up the problem. Is there any way I can help identify what the problem is
with the F33 default in a bug report or something so it can eventually be
addressed?
