OK. If you experience it again, please do

  M-x org-element-cache-reset

in the slow buffer and see if it is responsive again.

Another interesting test would be to try reproducing the problem with 
`org-element-use-cache'
set to nil.

I'm not totally sure this is related to the cache, as killing the buffer
should have solved the problem.
