Button text of tkinter does not work in mojave

Question

It is very simple program.

import tkinter
tkinter.Button(None, text='button').pack()
tkinter.mainloop()

I expect this program shows me such as a below picture.

But it shows a below picture actually.

When it is resized on GUI it seems working well.

It didn't occur this problem in High Sierra.

My environment is following:

• macOS Mojave 10.14
• Python 3.7.0

Could you advice to me?

I found out same problem on here.

Answer 1

Changing Appearance to Light Mode fixed this problem for me.

To change appearance, go to Settings -> General -> Appearance -> Light Mode.

Answer 2

I guess there is a bug in Tk. I am on MacOS 10.14.3 If you maximize and minimize the tkinter window the text on the button appears, another solution that worked for me is

from tkinter import *
from tkinter import ttk

button1 = ttk.Button(*your args here*)
