Description of issue

I get: _tkinter.TclError: bad option "variable": must be add, info, or remove, which is related to deprecated function: self.trace("w",..)
Correcting all occurrences in the source code of https://github.com/oscarpilote/Ortho4XP to: self.trace_add("write",..) doesn´t help! Still impossible to make previews and move the map. Unfortunately, it is very difficult to reproduce the issue with simple code example.
Interestingly, everything (as far as I can see) is ok on macOS Sequoia, with with Python 3.13 and 3.14 from python.org (self.trace("w",..) is accepted btw)

trace_add should work. trace/trace_variable indeed has been deprecated since 2016 (Python 3.6).

I suspect trace is not the only problem. Something weird is happening after correction, like ImageTk.PhotoImage cannot find the image when called from a complex function like this:
https://github.com/oscarpilote/Ortho4XP/blob/c5e0d4b50774de1850246fac56b9d461ae026a72/src/O4_GUI_Utils.py#L894
Simpler code works without problems
This is very specific for Homebrews Python 3.12 and 3.13 for Sequoia. Everything else works on Windows,Linux and Python from org on Sequoia.

There’s a threading issue also. Here’s an example code that reproduces the crash (_tkinter.TclError: image type "photo" does not exist) with Homebrew’s Python 3.13 on Sequoia 15.2, but works with any Python 3.11 or 3.13 from python.org:

(requires pillow)

import os
import tkinter as tk
from PIL import Image, ImageTk
import traceback
import threading
import queue

class Example:
    def __init__(self, root):
        self.root = root
        self.photo = None
        self.queue = queue.Queue()
        self.image_label = tk.Label(root)
        self.image_label.pack()
        self.check_queue()
        # Start the image loading process in a separate thread
        threading.Thread(target=self.async_build_map_layer, args=(37, 23, 11, "OSM", self.queue)).start()
    
    def check_queue(self):
        try:
            photo = self.queue.get_nowait()
            self.update_image(photo)
        except queue.Empty:
            self.root.after(100, self.check_queue)
    
    def update_image(self, photo):
        self.photo = photo
        self.image_label.config(image=self.photo)
        self.image_label.image = self.photo  # Keep a reference to avoid garbage collection

    @staticmethod
    def async_build_map_layer(lat, lon, zl, provider, output_queue):
        try:
            # Simulate loading an image file
            image_path = "absolute path to some .jpeg"
            background_map = Image.open(image_path)
            print("Image loaded successfully")
            
            # Simulate some processing delay
            import time
            time.sleep(2)
            
            photo = ImageTk.PhotoImage(background_map)
            output_queue.put(photo)
        
        except Exception as e:
            traceback.print_exc()
            raise e
