wrefresh() (or whatever) it calculates the number of cells that actually differ between the two, and only sends instructions to redraw those exact cells. You can force other behavior but this is the default.mvwprints all over the fucking code doesn't cause flickering`jed` text editor. But it makes ncurses look svelte. It's not so much an input/output library as an entire RAD platform.
