Thanks for posting this!

For Nicolas et al, my more general question about performance with
oc-basic was related to this, so you can ignore that.

As mentioned in the title, the lib.bib file is ~10MB - if I swap this out for a non-existent or tiny bibtex file the problem goes away, and the in-buffer citations are rendered in a red face. Clearly from this and the below profile the issue is something to do with checking etc the citations for fontification purposes.
