Do you get anything similar when running the console interpreter?

Assuming not, the difference between them is that Idle writes to the 
screen via a tkinter (tk) text widget.  You might try something like 
this to see if tkinter is generally not working, even when run without Idle.

import tkinter as tk

root = tk.Tk()
text = tk.Text()
text.pack()
text.insert('1.0', 'this is a test eeeccee')
