bug#14213: 24.3; Redraw artifacts with emacs cursor and highlighting

From: Chris Rose
Subject: bug#14213: 24.3; Redraw artifacts with emacs cursor and highlighting
Date: Mon, 15 Apr 2013 14:09:28 -0700

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

When editing text, I odd cursor shadows and leftover, un-redrawn text as
I type; for example, during the typing of this sentence the letters on
this line were often obscured by the cursor appearing over them, as well
as appearing on the current line.

I am running emacs as a daemon on a RHEL5 64 bit host, and running emacsclient 
there as well, using an Xorg server on Ubuntu 12.04
emacs daemon command line:
ssh -f -o ForwardAgent=no -o ForwardX11=no -o ForwardX11Trusted=no 
chrisros.desktop 'DISPLAY= nohup ~/bin/emacs -nw --daemon 2>&1 >/dev/null'
ssh -f chrisros.desktop '~/bin/emacsclient -c'

If I run emacs daemon with -Q, the issue persists:
ssh -f chrisros.desktop 'DISPLAY= nohup ~/bin/emacs -Q -nw --daemon 2>&1 
ssh -f chrisros.desktop '~/bin/emacsclient -c'

Image with emacs --daemon -Q: http://imgur.com/v7ZOKtA

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
