LLVM5 is actually a misnomer as explained here: https://build.opensuse.org/package/show/home:forkbomb:turboAMD-stable/llvm5 Also, even when Forkbomb and Factory were on the same version of Mesa, only Forkbomb's RADV-Vulkan worked. Upstream has suggested that it may have to deal with LTO: https://bugs.freedesktop.org/show_bug.cgi?id=99591#c6 .
