Bug#975687: xterm: loses text lines, even descenders from some lines
Package: xterm
Version: 362-1
Severity: normal
X-Debbugs-Cc: tg@mirbsd.de
I’ve got the following in my ~/.xinitrc…
/usr/bin/xterm +sb -fg black -geom 78x10+1+637 \
-bg slateblue -e top &
/usr/bin/xterm +sb -fg black -geom 90x11+475+637 \
-bg cornflowerblue -e tail -F /var/log/syslog &
… to monitor the system on my laptop.
Recently, I’ve noticed that the right (syslog) window reliably
loses some text lines when multiple lines end up in syslog in
the same second, which tail would then also output very quickly.
I can’t find these lines when scrolling up with Shift-PgUp,
and when I select them with the mouse the spook ends(the text
is shown, in inverse as usual, again and (when deselected) in
normal colour), so it definitively is a display issue in xterm.
I can somewhat reproduce it with “sudo true” given I have…
*.* -/var/log/syslog
… in /etc/syslog.conf.
The log lines in question (hard-wrapped to match xterm’s soft):
Nov 25 06:23:43 tglase-nb sudo: pam_unix(sudo:session): session opened for user root by tg
lase(uid=0)
Nov 25 06:23:43 tglase-nb sudo: pam_unix(sudo:session): session closed for user root
Nov 25 06:23:45 tglase-nb sudo: tglase : TTY=pts/2 ; PWD=/home/tglase ; USER=root ; COMM
AND=/bin/true
The line with 'TTY=pts/2' is the one that gets hidden, but,
interestingly enough, the descender of the “g” and “p” in
the line above (session closed) *also* go away.
~/.Xresources sets a pretty standard font:
XTerm*VT100*font: -misc-fixed-medium-r-semicondensed--13-120-75-75-c-60-iso10646-1
