cursor not erased in certain columns running emacs -nw in gnome-terminal

[Rob Ochshorn]

Binary package hint: emacs22

1) Ubuntu 8.04

2) emacs 22.1-0ubuntu10.1

3) when typing, the spacebar should always produce whitespace, and spaces should appear blank

4) using emacs -nw + gnome-terminal in any major mode with syntax highlighting (eg. lisp-interaction, html-mode, conf-mode, etc.), spaces in the 7th, 15th, 23rd, ... (7 + 8*n)th column are "sticky" in that the cursor does not erase immediately if a non-whitespace character follows. For example typing (not pasting!) the string:

123456 1234567 1234567 1234567 1234567

at the beginning of a line will produce cursor artifacts between each set of characters. forcing the window to redraw (eg. by covering it with another window) will correct the display. the error is not encountered when emacs is run in a screen session.

Usually, it is just the blank space, but this time, when I was trying to take a screen shot, it got much worse than usual.

Selecting all text or reopening the window will clear it.

There is a workaround in
http://community.livejournal.com/ubuntu_users/307544.html?thread=2193240#t2193240

Turn on column-number-mode.
You can put the following into your ~/.emacs to have it on on loading
(setq-default column-number-mode t)

I couldn't reproduce this problem in emacs23.3.1 on Ubuntu 11.10. Can you still reproduce it?

[Expired for emacs22 (Ubuntu) because there has been no activity for 60 days.]

I am experiencing the same issue in emacs 24 from Raring.
