corner_radius: (visual issue) corner_radius Implementation Not Rendering Rounded Corners properly

[1contra]

I'm encountering an issue with the corner_radius implementation in CustomTkinter. When setting a corner_radius value for a CTkEntry (or other widgets), instead of rendering rounded corners, the corners are being drawn with the background color, resulting in a flat rectangular appearance.

With a solid background in applications, the rounded corners render as expected, and the behavior is correct. However, when using custom video backgrounds or images, the corners do not display as rounded. They instead appear flat and are drawn with the background color, which doesn't look visually appealing and breaks the design aesthetic.

This issue significantly impacts the user interface when custom backgrounds are used, and it creates an inconsistency in how the widget looks across different backgrounds.

I've included screenshots below to show how the widget looks with the custom backgrounds:

Greetings.
I am also facing a similar issue with the corner_radius attribute. However, mine doesn't even work properly on a default background (no custom image), it just makes my CTk element look like a bone. Check my issue out below:
