--- Comment #5 from Timothy Arceri <t_arceri at yahoo.com.au> ---
Here are some really quick instructions for building mesa and bisecting the

Get and Build RADV:

git clone https://gitlab.freedesktop.org/mesa/mesa.git

cd mesa

sudo dnf builddep mesa (this is how you get the mesa build deps on Fedora not
sure how you would do that on Arch)

sudo mkdir /opt/xorg
sudo chown youruserid /opt/xorg

./autogen.sh --prefix=/opt/xorg --with-dri-drivers="" --enable-gles1
--enable-gles2 --enable-shared-glapi --with-gallium-drivers=""
--with-vulkan-drivers=radeon --with-egl-platforms=x11,drm  --enable-gbm
--enable-glx-tls --enable-dri3

make -j4 && make install

Use your built version of RADV:

Add the following to ~/.bashrc and logout and back in (Remember to remove this
if you want to switch back to your system version of RADV)

# User specific aliases and functions
export VK_ICD_FILENAMES=/opt/xorg/share/vulkan/icd.d/radeon_icd.x86_64.json

Bisecting the issue:

Here is a simple intro to git bisect http://webchick.net/node/99

The hardest part will probably be finding a commit that works. From there it
should be straight forward. Maybe start with the 18.1 branchpoint 
6754c2e83d79f93b3a4c8 (that was the end of april)

Good luck.
