Does forcing DRI3 via "export LIBGL_DRI3_ENABLE=1" or building
graphics/mesa-{libs,dri} with CFLAGS+=-D__DRM_NEXT__ help?

Xwayland needs DRI3 but FreeBSD disables it as a kludge for drm-legacy-kmod:
  graphics/mesa-dri/files/patch-src_glx_glxext.c
  graphics/mesa-dri/files/patch-src_egl_drivers_dri2_platform__x11.c
