Maybe a TitledPane bug

[David Grieve]

It's hard to tell without some short, self-contained, correct example. 
This sample I crafted here doesn't reproduce the issue.

@Override public void start(Stage primaryStage) {

     final TitledPane titledPane =new TitledPane("Button Pane",new Button("Button"));
     final HBox root =new HBox();
     root.getChildren().add(titledPane);

     primaryStage.setTitle("Maybe a TitledPane bug");
     primaryStage.setScene(new Scene(root,300,250));
     primaryStage.show();

     final Region titleNode = (Region)titledPane.lookup("*.title");
     titleNode.setBackground(new Background(new BackgroundFill(Color.GREEN,null,null)));
}
