I restarted and spent a minute or two with one buffer, closing and expanding headings, and just moving around without typing, and it quickly slowed down. When I did do a bit of typing it was very laggy (and will only get worse). The profiler said this:

I spent a while with git bisect this afternoon and the problem (for me) started here:
commit 5d186b499dde97f59a91dc11f4c4a15113d29f4d
Author: Ihor Radchenko <yantar92@posteo.net>
Date: Sun Feb 25 11:42:44 2024 +0300
org-fold: Refactor fontifying newlines after folds
That seems to fit with some of what the profiling showed, in that it's about font-locking, though why LaTeX is mentioned is beyond me. When I was going through the bisect process I wasn't testing on files with LaTeX, I was expanding and folding some I regularly use that have some code blocks and tables with a few hundred lines.
My Lisp isn't good enough to see why this commit might have changed behaviour. A couple of people had slowness caused by a spell-checker that was easily fixed ... has no one else seen a problem dating back to late February? Ihor, does this suggest anything to you? Is there anything else I could try?
