I've just spent the day using mutt on gnome-terminal for the first time since I reported this, and it appears fine now - I guess it got fixed somewhere in the last year or so. It also seems to stand up to a cat /bin/ls in a terminal window with out any droppings being left behind.
For the record, my current terminal setup is 'use system terminal font'. Thanks; please close the bug. Dave -- Corrupt display with Mutt https://launchpad.net/bugs/15193 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
