I have a tkinter window that I have given a background picture by creating a Label widget with a PhotoImage instance (referencing the image instance through Label attributing).
However when I run the script and move the main window below the start menu (am using Windows 10) or past the sides of the screens for even one moment, all the widgets packed onto the Label (w/ background pic) completely disappear.
They only come back (somewhat) upon hovering over them with the mouse it seems. Also the background picture remains and continues to fill the screen. Could it be that the background picture Label is being "lifted" and makes it seem like the widgets are disappearing? If so, how can I prevent this from happening?
The fix that I have found for now is to not use a Label with a PhotoImage as the parent "frame", but instead use a typical Frame widget with only a background color, but this is not ideal.
import tkinter as tk
root = tk.Tk()
root.geometry('600x350+600+300')
root.resizable(width=False, height=False)
boxBg = '#666'
frameBg = '#fff'
#problem method
backgroundImg = tk.PhotoImage(file='program_media/background.png')
bgFrame = tk.Label(root, image=backgroundImg)
bgFrame.image = backgroundImg
#less than ideal solution so far
#bgFrame = tk.Frame(root, bg='#fff')
bgFrame.pack(expand=1, fill=tk.BOTH)
mainFrame = tk.Frame(bgFrame)
mainFrame.pack(side=tk.TOP)
title = tk.Label(mainFrame, text='Test String')
title.pack(side=tk.TOP)
#widget creation code packed within mainFrame
#...
#... All these widgets (including mainFrame above) are disappearing
#...
#end of widget creation code
root.mainloop()
See what I mean in this screenshot of BEFORE and AFTER moving the main window below the start menu.
