It's unlikely to be a package directly causing it, but it may be doing
something which causes a bug in Emacs itself to show.

The usual way would be a binary search type strategy. Comment out half
your config, then see if you still have the problem, if not try the
other half. Then you half what remains, and repeat until you've found
the cause.

The problem is that it may be a combination of things that are causing
it, but at least it may give us a chance to get a minimal recipe to
replicate the bug.
