 Running curses applications under term and ansi-term is broken
Date: Thu, 05 Dec 2013 10:17:15 +0000

Hi,

When I run curses applications (such as htop and Linux's "make
menuconfig") in term and ansi-term the window's width appears to be
detected incorrectly. This causes curses to emit lines that are too long
for the window and thus Emacs spans them over more than one line. This
quickly makes the terminal output unreadable. Note, this is a visual
observation, I haven't looked at the code.

Recipe:

emacs -Q
M-x term
<ret>
htop

Thanks,
Matt

I can't reproduce this using the recipe given.  Are you still seeing
this on a modern version of Emacs?

If I don't hear back from you in a couple of weeks, I'll just assume
this has been fixed and close this bug.

Best regards,

Indeed, I can't seem to reproduce this myself using Emacs git.  This
must have got fixed at some point.

Please feel free to close.
