Test application code and screenshot

If using ncurses library and call one of read methods (Console.ReadLine(), Console.ReadKey() or Console.KeyAvailable) inside ncurses block

initscr();
... <- somewhere here
endwin();

then terminal will be messed up (its settings will be broken). To restore it user can use a `stty sane` command.

Found workaround: if call Console.KeyAvailable BEFORE ncurses initialization, all works fine:

bool ignored = Console.KeyAvailable;
initscr();
... <- using or not using read methods
endwin();

This is expected, as Console will restore the settings that it read previously and will not know that you changed those behind its back.
