Missing edges

When doing F6 with show edges enabled there seem to be missing edges. For
example here is a tube unioned with a flat plate.

Why is there not a circle of edges where the tube intersects the top
surface of the plate?

Similarly, looking into the tube there are missing edges.

To answer my own questions, I think I have probably asked it before. The
missing edges are drawn on the inside. Can this be fixed?

Is this an aliasing effect? Does moving the object around, and changing
viewport make any difference?

No, it's consistent. It seems the concave edges are drawn on the wrong
side, or at the wrong time.
