OptionMenu in fullscreen with touchscreen doesn't work

[szubakwarc]

Hi.

I am developing appusing customtkinter on rapsberry pi 4b with touch screen and I stuck on OptionMenu probem. The problem is that when I open the application in full screen (by various methods) it causes the drop-down menu to be unresponsive. It expands when touched, but I can't select any of the items, whereas when I use the mouse everything is ok.
I am anxious to use this widget, so ideas on what could be wrong and how to solve this problem are welcome. Sample code below:

import customtkinter as ctk

root = ctk.CTk()
root.title("CustomTkinter Example")
root.geometry('600x400')
'''
root.attributes("-fullscreen", True)

screen_width = root.winfo_screenwidth()
screen_height = root.winfo_screenheight()
root.geometry(f"{screen_width}x{screen_height}+0+0")
root.overrideredirect(True)
'''
root.bind_all("", lambda e: root.destroy())

def update_label(event):
label.configure(text="Selected Option: " + optionmenu.get())
options = ["Option 1", "Option 2", "Option 3"]
optionmenu = ctk.CTkOptionMenu(root, values=options, command=update_label, font=("Arial", 20), dropdown_font=("Arial", 20))
optionmenu.pack()

label = ctk.CTkLabel(root, text="Selected Option: ", font=("Arial", 20))
label.pack()

if name == "main":
root.mainloop()
