You can try setting org-highlight-latex-and-related to '(latex) instead of
'(native).
Even with this setting, latex fontification in special blocks is slow. The
reason being that the whole block has the `font-lock-multiline'
property, hence
every char insertion triggers refontification of the whole block.
In the function `org-do-latex-and-related', I commented out the second
condition
of the `cond' form, which makes calls to `face-at-point'. This yields a
significant speedup, and was enough to make things bearable in my cases.
You can
also try to simplify the latex regexp.
If you try these, I'd be interested to hear how much of an improvement
theymake.
Regards,
