In my humble opinion, can you guarantee that this code will not be called repeatedly? Maybe it only needs to be called once?

Add a print statement to your code and just try the code below:
from tkinter import messagebox
messagebox.showinfo("info", "test")
messagebox.showinfo("info", "test")Then you'll find that it runs twice.

Refer #119459 , we believe this is a tk/tkinter bug that should be fixed in tkinter. In this PR, I added the fix code to
tkinter/__init__.py, which fixes the window blurring problem that every program that uses tkinter has. Since I had already committed fix for turtledemo and terryjreedy fix IDLE earlier, I removed them here. Also #119175 was backported to 3.12 3.13 and I think this PR should be as well.↓Fix
