Hello! I was playing lizardmen earlier and noticed that when using the 3D 'Porthole quality' graphical setting that Lord Kroak's in-battle porthole is replaced with fog. His 2D porthole is properly implemented and the 3D version shows correctly on the campaign map, but not in battle - see attached images.
