I built and installed amdvlk-vulkan-driver from
https://github.com/GPUOpen-Drivers/AMDVLK, though, and now it works
flawlessly. Can someone who knows about this explain to me what the
situation is? How does this external driver relate to what we have in
Fedora?
There are four Vulkan driver options for AMD graphics chips at this time.
* Mesa RADV - LLVM (default up to version 20.1)
Original Vulkan driver produced by the Mesa team.
* Mesa RADV - ACO (default starting in version 20.2)
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.
Hope that helps,
Michael
