在 tkinter 中单击时，有没有办法阻止带有图像的按钮闪烁？

Question

When creating a button with an image on it you can specify its background color to be the same as the root background color with the bg='color' parameter so that if you have an image with transparent background the result seems nice. However for some reason when you click on the button, there is a white flash that covers the button for as long the click happens.

I have this code:

from tkinter import Tk, Button
from PIL import Image, ImageTk

root = Tk()
root.config(bg='black')

image = Image.open('your_image_file').resize((50, 50))
image = ImageTk.PhotoImage(image)

button = Button(root, width=50, height=50, image=image, bg='black')
button.pack()

root.mainloop()

After importing PIL (if not already) and then filling the appropriate path name to your image the code should run without any problems
Notice that when you click the image a whity flash that covers the button appears?

I want to get rid of that
I've tried passing the parameters highlightcolor highlightbackground and highlightthickness and playing around with them but nothing really changes whether I for example change highlightthickness=0 or highlightbackground='blue'
Is there any way to do that properly?

Thanks in advance!

Oh, I just now realised the activebackground parameter does the job Everything okay now I can modify the whity flash color:P
