Just so you know, the system is running xorg-server 1.18.3 and 
xf86-video-amdgpu-1.1.0 with DRI3 + xf86-input-libinput-0.19.0.

I'm rebuilding LLVM and mesa now with debug enabled just to make sure my 
environment is sane (LLVM didn't have debug/assertions enabled), but 
that'll take a while... be right back with Xephyr testing when that's 
done.
