Comment:
@Anachron are you using any Mesa environment variables to override behavior such as `MESA_LOADER_DRIVER_OVERRIDE`?  https://docs.mesa3d.org/envvars.html#core-mesa-environment-variables

Perhaps the wrong driver is being selected.  The i915 driver is gallium-only so there is no i915g driver anymore.  i915 IS the gallium driver.  In the past there was i915 and i915g.
