I'm not sure that's a very good title for this email, but it's what I've

Since configuring my environment to use UTF-8, I've had a problem while
checking email on a server. I log into the server via SSH, then enter
the `mutt` command. As I page through the inbox, open and close emails,
et cetera, I get a bunch of junk on the screen -- characters from the
previous screen appearing on the current screen. I have to use Ctrl + L
to clear it up and return the appearance of the screen to the way it's
supposed to look.

What can I do to eliminate this problem? I don't want to have to force a
screen redraw every time I switch between views, scroll down a page in
mutt, and so on. I also don't want to go back to a character set limited
to plain ol' ASCII (there's a reason I use rxvt-unicode instead of rxvt).

Don't see it here. If you are sure that mutt uses UTF-8 charset (ie,
forced it with 'set charset="utf-8"'), make sure it's linked against
ncursesw library (and not just ncurses) - need to use WITH_NCURSES_PORT
on 6.2 and earlier or build it using WITH_SLANG.

I finally got around to checking the settings in the Makefile and
recompiling mutt. End result: same problem. If anyone else has any
ideas what might be causing this problem, please let me know.

addendum: The computer I'm using as a client to access mutt on another
machine doesn't have this same problem locally. When I open a local mutt
instance, there's no junk on the screen. I decided to try using SSH
through the remote system where I'm encountering this issue, then from
there using SSH to get back to the local machine, and opened mutt inside
this contrived SSH loop. Still no problem. Thus, whatever the problem
is seems to be particular to the remote machine.


What is your TERM environment variable setting? Are the terminfo
files on the remote system current?

The TERM environment variable on both systems is set to `rxvt`. I'm not
sure what I should be looking for to be sure the terminfo file is
correct.



I'm reasonably sure that mutt uses ncurses, and if it is not
built correctly, that could also cause problems.

I have tried both the default (WITH_SLANG=yes) and WITH_NCURSES_PORT=yes
on the remote system. Otherwise, I haven't mucked about with the
Makefile of mutt at all.
