VSync is disabled, so you get more than 60 FPS. Looks generic to OpenGL under
X11 -> reassigning. I've never used an AMD GPU myself, so may not be aware of
quirks.

67df (Polaris10) is listed in both drm-kmod and mesa-dri, so OpenGL
acceleration should work.

Can you show "dmesg" output? If you have amdgpu_load=YES in /boot/loader.conf
convert to kld_list=amdgpu in /etc/rc.conf. Modern GPUs need to load firmware
which may not work from loader(8).

xf86-video-vesa doesn't support OpenGL acceleration. Maybe deinstall all
xf86-video-* except xf86-video-amdgpu to facilitate debugging.
