A simple reprod code: import tkinter as tk from tkinter import font
root = tk.Tk()
root.minsize(1280, 800)
root.bind('<Escape>', lambda _: root.quit())
my_font = font.Font(root, 'Sans 128 bold')
f_1 = tk.Frame(root)
tk.Button(f_1, text='Frame 1', font=my_font).pack(
expand=True, fill=tk.BOTH)
f_2 = tk.Frame(root)
tk.Button(f_2, text='Frame 2'[::-1], font=my_font).pack(
expand=True, fill=tk.BOTH)
f_1.pack(expand=True, fill=tk.BOTH)
current = f_1
def flip():
global current
current.pack_forget()
if current is f_1:
current = f_2
else:
current = f_1
current.pack(expand=True, fill=tk.BOTH)
root.after(1000, flip)
root.after(1000, flip)
root.mainloop()
