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.

I'm currently using Python v3.12.1 and still have the same issue:

[juanjguerrer]

Did you solve it? Im facing the same issue on Ubuntu, using python 3.10.8

[DenishKakadiya]

I'm getting the same issue on Ubuntu, using python 3.12.6.

Any widget with round corners is rending wierdly.

In click button in image, I have set corner_radius=50 to visually enhance the issue.

[DenishKakadiya]

Found temporary hack from a comment by @sbhanji in [(https://github.com//issues/1384)] thread which make corners litttle better, but still not smooth rendering.

add: customtkinter.DrawEngine.preferred_drawing_method = "circle_shapes"
