I don't think I can reproduce this here, at least not in "emacs -Q". But it's hard to say because you didn't tell which part(s) of the previous contents I should watch, and there's a lot of stuff on the screen to be sure that none of it was left behind. So please describe the recipe in more detail: . to what width to resize the frame . how do you "move to the end of a truncated line" . which parts of the display are left on the screen Thanks.
