Rendering issue

[krish0307]

I'm trying to run this simple example code to render a button. When I run the program, I see GUI like this

Could someone shed light on what is causing this issue?

System Information NAME="Red Hat Enterprise Linux Server" VERSION="7.9 (Maipo)" ID="rhel" ID_LIKE="fedora" Kernel version- 3.10.0-1160.81.1.el7.x86_64

echo $XDG_CURRENT_DESKTOP= GNOME

**Code ** import tkinter import customtkinter

customtkinter.set_appearance_mode("System") # Modes: system (default), light, dark customtkinter.set_default_color_theme("blue") # Themes: blue (default), dark-blue, green

app = customtkinter.CTk() # create CTk window like you do with the Tk window app.geometry("400x240")

def button_function(): print("button pressed")

button = customtkinter.CTkButton(master=app, text="CTkButton", command=button_function) button.place(relx=0.5, rely=0.5, anchor=tkinter.CENTER)

app.mainloop()

Upon running simple_example.py, this is the GUI

I'm also a fedora user. This is Linux specific issue. It can be resolved by upgrading your python version to 3.10.
