I do not encounter the problems you said.
% mutt -v | head -n 1
Mutt 2.0.6 (2021-03-06)
% vim --version | head -n 1
VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Mar 31 2021 00:16:48)
% cat /usr/pkgsrc/CVS/Tag

Do you use the same pkgsrc version for both apps and their dependencies?

Is it wsvt25?

Alright, it is xterm.
That means you did ssh to NetBSD server. I would suspect your network.
Do you ssh over WiFi or hard wired cat5e? Is NetBSD server on VM?
Have you tried logging in directly on NetBSD host and had the test there?

Well, rendering is fast. Is redirection slow?

AFAIK, NetBSD only supports libcurses, there is no ncurses in NetBSD.

Does your terminal have some settings like "Delete sends Ctrl-H"?
Does Ctrl-U delete the entire line?
I'm not sure if I do get your question.
