unfolding is delayed in relatively small file

Hi everyone,

I just updated to recent main branch of org-mode with the new org folding
engine. My emacs is from git, but somewhat out of date (2022-05-08).

WIth a relatively small test file, I find that folding and unfolding a
subtree with children does not cause a redisplay unless I alt-tab away from
my Emacs window and then alt-tab back.  "FOLDED" or "SUBTREE NO CHILDREN"
will echo in the message area, but the state of hte buffer won't change
until I switch focus.

I haven't done any extensive testing yet, and have many third party
packages installed. I've also just now noticed that this behaviour is
somewhat intermittent, and somehow I managed to make it stop briefly in
my   MWE, but I don't seem to be able to trigger the shift back to normal
behaviour in a "real" org file.

I'm wondering if anyone else has seen this and what you've done to fix it!

Thanks,
Matt


MWE:


* fold me

some text
** some more text
let's see what's happening.
** test again
