Cluster culling should work, my suggestion for disabling just small
feature culling is all that should be required to fix things.

The bounding sphere of the geometry will be projected into screen
space, if its smaller than the small feature cutoff size then it'll be
culling. A single point geometry will have a bounding sphere of 0
radius so will be culled.
Yes, it all works now. There was a mistake in my code. Sorry for the bother.
