This will be available for Linux too in FlatLaf 2.1 (see #482)

Please try the latest snapshot: https://github.com/JFormDesigner/FlatLaf#snapshots

To enable it use:

if( SystemInfo.isLinux ) {
    // enable custom window decorations
    JFrame.setDefaultLookAndFeelDecorated( true );
    JDialog.setDefaultLookAndFeelDecorated( true );
}
