Matthew Flatt a2e217a846 racket/gui win32: reset canvas backing size when scroll bars change ... Avoids a gray box at the bottom of the GRacket REPL window on startup, or in DrRacket when a horizontal scroll is automatically removed due to, say, hiding a interactions window positioned to the right of the definitions window (where the definitions content is narrower than the whole window but wider than half).
