Feedback Wanted: High Definition Render Pipeline

Are the draw modes for the scene currently working properly for hdrp or are they in flux? Its related to Progressive GPU Lightmapper preview page-2#post-3754222 in that I cant view the sceneview for uv overlap to display any meaningful information, nor lightmap preview for uv overlap which doesnt show anything just a “Loading…” text where the lightmap image should be(as I get some console warnings about overlapping uvs which I believe is the texel overlap rather than uv overlap).
