I just bisected similar issues in Team Fortress 2 (which also uses the Source
engine) to the commit below. Looks like we're doing something wrong for clip
vertex support.

    radeonsi: Don't leave gaps between position exports from vertex shader

    If the vertex shader exports clip distances but not point size, use
    position exports 1/2 instead of 2/3 for the clip distances. Fixes
    geometry corruption in that case.
