On windows the native window decorations are overwritten by a custom title bar, which still replicated the look of the native window buttons to blend into the operating system.
In contrast to simply setting
frame.setUndeocorated(true) native window snapping, taskbar preview and other features, which decorated frames profit from, are still available.
You can disable the custom decorations by setting LafManager.setDecorationsEnabled(false) or passing -Ddarklaf.decorations=false to the JVM (equivalently setting System.setProperty("darklaf.decorations", "false")).
