I'm pretty baffled by this one. I can reproduce it using
gnome-terminal, and a slightly different version of the bug seems to
show up in Emacs 22 too. Anyone have any idea?

All those use the libvte terminal emulator widget underneath.
It _may_ be some issue with that rather than emacs, there is an
unconfirmed bug report of various redraw issues in recent vte
when cursor positioning is used:

I can reproduce something like it with xfce4-terminal with
emacs -nw -Q
Without -Q, I have my usual non-default dark blue background set on my
default face in emacs, and then the block artifact doesn't appear,
so maybe there's some place (whether in emacs or the vte widget I don't
know) where a background redraw is being skipped when it shouldn't be,
probably as an optimisation for the terminal-default background case.

Probably that's http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=457483
aka http://bugzilla.gnome.org/show_bug.cgi?id=514632.

I can confirm that upgrading to the latest version of vte fixes the problem.
Old vte version 0.17.4
new vte version 0.19.4
Best regards

Thanks. Looks like the Gnome-terminal maintainer has fixed this in SVN.
