multiblock disable normals for rendering
When grouping a sphere and a line in a multiblock normals are not used for rendering anymore. Interesting this does not happen if you group two spheres or even a sphere and a point. This happens in the 5.9 and 5.9.1 RC1 but does not happen for 5.8.1.
See the attached picture and state file. Left view shows the multiblock containing the sphere and the line, right view shows the original sphere and the line
