Always compute CD_ORCO undeformed coordinates now for rendering, same as before. There is still a refresh issue to be fixed, when switching from solid to textured mode in the viewport. Computing such undeformed coordinates can be expensive and is not actually needed if the mesh is only using e.g. UV maps. This was the same in 2.79, at least now we are skipping the computation when there are no deforming mdifiers on the mesh.
