> Per jbeich swrast_dri may indicate an issue with llvmpipe

Originally discussed on 2021-06-05 at #helpdesk on Discord. Other details:
- llvmpipe is used due to lack of DRM per https://github.com/freebsd/drm-kmod/issues/84
- Dan tested on aarch64 (Cortex-A72) but I couldn't reproduce via LIBGL_ALWAYS_SOFTWARE=1 on amd64+i386 (Skylake)
