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: http://bugzilla.gnome.org/show_bug.cgi?id=528077 >> Cannot reproduce with >> linux console (term=linux || term=xterm) >> xterm (term=xterm || term=linux) > > I'm pretty baffled by this one.

Anyone have any idea? > 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.
