The bug
Certain blocks do not cull the top face of the fence block. Many blocks, such as all solid blocks, do cull this correctly, however some non-full blocks do not. Also affects walls to some extent.
The following have been tested:
Lantern
One sea pickle
Pressure plates (all 9 types)
Potted plants (all 25 types)

I don't think you mean cull or culled since those words don't mean what your trying to say.

yes they do.

This can also be seen when placing a dragon egg above a fence.
