I've been using neomutt. On ASCII it was renamed to mutt, on Beowulf
they named it back to neomutt, and the mutt package is actual mutt. I
dunno which one you are using.

ASCII was on my old desktop, and Beowulf is on my new super desktop. I
use a local IMAP server running on the same computer in each case. The
ASCII version on the old computer would do that sort of mysterious pause
where all you can do is wait for it to unpause. The Beowulf version on
the new computer does that rarely. It was very annoying under ASCII, not
so much under Beowulf.

I use fetchmail to gather emails from my various email providers, that
dumps them into my local IMAP server.

I suspect the difference was the computers, not the version of neomutt.
Or it could just be if the check of IMAP stumbles across the fetchmail
process updating the IMAP folders. Or perhaps this later version mostly
fixed that pause. Maybe some combination of the three.

The Beowulf version does have a problem with showing the O old email
marker as N new email (a known bug). Which is even more annoying. I'm
considering installing ASCII in a VM on this new super desktop, and
running the ASCII version in it. If I do that, I might find out if the
pause gets worse.

(For reference, old computer was an 11 year old AMD system with 8 GB of
RAM, new super desktop is an AMD Threadripper with 256 GB of RAM.)

A big old stinking pile of genius that no one wants
coz there are too many silver coated monkeys in the world.
