Performance should always be better with cacheBuffer
Setting a cacheBuffer introduced more work for the scenegraph due to
cached delegates' visibility being toggled. Changing visibility is
expensive as it is proagated to all children. Introduce a cheap
method of hiding a branch instead.
Also avoid initiating incubation in the same frame as a completed
creation.
