I couldn't reproduce the bug with Athena, GTK+ 2, GTK+ 3 GUIs, but did with MacVim, although I'm not sure which X11 GUI the reporter meant by that doubly quoted word, "regular." I wish the description could be more specific in order to save other devs' time.
As to the mentioned "-1H", it looked to me that it was part of a piece of control code with CSI chopped off. Accordingly, I guessed it's original form was "ESC|-1H" (= stop highlight forcefully cf. screen_stop_highlight() of screen.c). Along that line, I dug into the issue and arrived at gui_write() of gui.c. What I found there was, when a given control code had a parameter and the parameter was a negative integer, the function was unable to handle it correctly. IOW, because the minus sign in "-1H" was not considered as part of an integer by the function and was not handled in the succeeding switch statement as control code either, "-1H" was eventually passed to GUI as ordinary text and appeared on the screen. The attached patch should fix our own issue I've just described, and hopefully, resolve the MacVim issue, too.
