           Summary: Xorg Graphical Corruption when using anything Vulkan
                    on Navi10
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Vulkan/radeon

example of font corruption

Fedora 30, with Kernel 5.1rc1
Mesa 19.2.0-0.25.git915abbe
LLVM 10.0.0-0.1.r366635
GPU RX 5700XT (navi 10)

Usual desktop usage with the above packages is fine, but as soon as user loads
anything that makes use of RADV (Steam Client, anything in DXVK) xorg starts
visually corrupting, black boxes around things like firefox windows, fonts turn
into boxes. Corruption is not resolved until a reboot

Does not happen with mesa-vulkan-drivers packages are removed and replaced with
amdvlk equivalent

Multiple users on Arch Forums and Reddit report similar experience
