I see.

I don't know anything about forward search.

I don't know. I wonder what changed between 2.1.4 and 2.2.0. If you
wanted you could try 2.1.4's configure.py with 2.2.0. I do not recommend
this at all. My guess is something would go quite wrong.
Another thing to try would be to do a git bisect. You would need to
compile LyX though.

Or you can wait a few days and see if someone responds with a better
idea.
