There is currently a bug in older ncurses versions (like on OpenBSD) where a fix for a bug with REP is not backported yet. Most likely in tty/tty_update.c: Noticed while using lynx (which uses ncurses/curses). To reproduce using lynx: echo "Z0000000" | lynx -stdin or using the program: int main(void) { WINDOW *win; win = initscr(); printw("Z0000000"); refresh(); sleep(5); return 0; } This prints "ZZZZZZZ" (incorrectly).
