Intel doesn't use VAAPI from Mesa but EGL interop failing is concerning.

I can't reproduce.

Did mpv --hwdec=vaapi work fine with Mesa 18.1.*? Can you show vainfo
(from libva-utils) output? Can you try -vo vaapi just in case?

Does MOZ_ACCELERATED=1 alone work? Can you check WebGL2 in about:support?

drm-legacy-kmod or in-base DRM bits in FreeBSD base don't support Vulkan.
drm-{stable,next,devel}-kmod do support Vulkan on AMD and Intel. On Intel
anything older than Haswell is unknown and according to Wikipedia there's no
Vulkan support on SandyBridge at all. Besides, i915kms.ko doesn't support
userptr (at least on drm-stable-kmod atm) outside of root[1]. Even after
applying ANV workaround[2] only few apps work: vulkaninfo, ppsspp but not
vkquake, rpcs3, mpv --gpu-api=vulkan.

RPCS3 requires OpenGL 4.3+ support but as SandyBridge is 6th generation
of Intel iGPU you're limited to OpenGL 3.3. Unfortunately, the port cannot
run under software rendering as llvmpipe is also limited to OpenGL 3.3.
