Remove start_screen() and end_screen() from the Window-port interface. They were only ever used by tty, and there was a comment carried to several window-ports about how they "really should go away. They are tty-specific" term_start_screen() and term_end_screen() are part of terminal/NO_TERMS supporting routines now.
