getch acts weirdly (cursor keeps moving, like it's running inside a loop)

Same problem here. After a call to getch the cursor starts to constantly move down line by line.

Here is a program to reproduce the behaviour:

require "ncursesw"

Ncurses.initscr
Ncurses.addstr("Cursor starts to move down!")
Ncurses.getch # Wait for a keypress to quit
Ncurses.endwin

System:

• Linux Mint 17 (64-bit)
• Ruby 2.0.0-p481
• gnome-terminal 3.6.2

adding Ncurses.cbreak
after Ncurses.initscr

will stop this from happening
