Hi,
Yes, this is much, much better with this patch. I don't experience any
noticeable slowdown anymore, whether in the test file or in my "real
world" file. Thanks!
Best regards,

Sure, see the attached file. As I said, it's a file filled with lipsum
with a single equation at the bottom.
AUCTeX's fontification for math went through a bigger overhaul. Please
share the file and a recipe (preferably starting with `emacs -Q') how to
trigger your obeservation, that would help a lot.
1. Open the file and go to the equation at the bottom
2. Notice that editing speed inside the equation is normal (e.g. hold
the space bar inside the equation and notice that it goes at a
normal speed)
3. Add a double prime somewhere in the equation, e.g. after the 2 so
that it becomes 1+1=2''
4. Notice that now editing speed is degraded, for example hold the
space bar at the end of the equation and notice that there is now a
stutter. If your CPU is too fast and you don't notice the stutter,
you can just copy more paragraphs of lipsum, I guess.
In my real life example (that I cannot share because the article in
question is not public yet) the slowdown is so bad that a single
keystroke inside an affected equation can take several seconds.
Thank you for providing concrete example and procedure to reproduce. I
experience the slowdown you described.
The attached patch fixes, or at least reduces, the slowdown on my side.
Could you check whether it works for you or not?
Best Regards,
Ikumi Keita
