Description of the issue

There is no such problem in the normal non-maximized state.

When I set the TransparencyLevelHint="AcrylicBlur" of SukiWindow, the edge will also become transparent or blurred. When I delete this attribute, it will become dark gray, and when I adjust the system theme to Light, the edge will also become white synchronously.

Package Version

6.0.0-rc

Environment

MacOS 15.2

Expected Behavior

Maximize the perfect display.

Reproduction

On MacOS use SukiWindow and then maximize the window.
