I've narrowed it down to this, which is much simplified version of what my code
+ ControlsFX was doing; it consistently reproduces the issue.
No third party libs needed.
public class DisappearingWindowIcons extends Application {
@Override
public void start(Stage stage) {
BorderPane root = new BorderPane();
root.setTop(new HeaderBar());
Button button = new Button("Click me for "bug" (hover of window icons
after)!");
button.setOnAction(_ -> bug(root));
root.setCenter(button);
stage.setScene(new Scene(root, 300, 200));
stage.initStyle(StageStyle.EXTENDED);
stage.show();
}
public void bug(Pane parentPane) {
StackPane stackPane = new StackPane();
Parent originalParent = parentPane.getScene().getRoot();
parentPane.getScene().setRoot(stackPane);
stackPane.getChildren().addFirst(originalParent);
}
}
Note that I see some CSS errors, that weren't being logged before for me (at
least not consistently, though I did see them):
