[issue38898] Tkinter checkbutton switch on and off together

[zaza hohonini]

New submission from zaza hohonini <zazahohonini at gmail.com>:

Hello,

I am running python 3.8.0 and found a problem where multiple checkbuttons get switched when I click one. From observing it looks like each first check button in a frame is linked. And each second, etc. I ran the some program in python 2.7.17 and it works as expected.

Basic program that show the problem:

import tkinter as tk

class Hello(tk.Frame):                     
    def __init__(self, parent=None):
        tk.Frame.__init__(self, parent)
        check = tk.Checkbutton(self, text='Checkbutton')
        check.pack()

root = tk.Tk()
Hello(root).pack()
Hello(root).pack()
root.mainloop()
