Description Robert Watson freebsd_committer freebsd_triage 2000-09-16 15:40:00 UTC 
When running more on a stdin stream, resizing the xterm results in an
incorrect redrawing of the screen -- the current byte count appears both
over-writing the first line, and on the last line as expected.  This
example comes from a cvs update -dP |& more

byte 1869U UPDATING
M contrib/amd/include/am_defs.h
U contrib/diff/util.c
U etc/MAKEDEV
U etc/Makefile
U etc/crontab
U etc/newsyslog.conf
...
U release/sysinstall/tcpip.c
U release/texts/HARDWARE.TXT
byte 1834

Fix: 

Not attached.
How-To-Repeat: 
In an xterm, run some streamed something (cat /usr/src/sys/kern/vfs_syscalls.c
|& more).  Resize the xterm part-way down the stream.  It seems to be
quite reproduceable in my environment, using kwm as the window manager.

This behaviour still exists, but the bug report should probably be
sent to the less developers, since less is maintained externally to
FreeBSD.

This behaviour still exists in FreeBSD 7.0-CURRENT with Xorg 7.3.

The system I'm using is:

uname -a:
FreeBSD muon.draftnet 7.0-CURRENT FreeBSD 7.0-CURRENT #0: Fri Sep 14 
23:03:19 BST 2007     
brucec@muon.draftnet:/usr/obj/usr/src/sys/INSPIRON  amd64

xorg-apps-7.3
xorg-cf-files-1.0.2_2
xorg-libraries-7.3_1
xorg-server-1.4,1
xterm-229

less 406

The problem occurs using both xterm and Gnome Terminal.
I didn't see anything that looked similar on 
http://www.greenwoodsoftware.com/less/bugs.html so I've sent an email to 
the maintainer.

less v408 was MFC'ed to RELENG_6 which fixes the problem.
