Works for me on Mac and Windows The only differences is that on Mac, the text stroke is a bit wider (note we are not using the same font on mac and win) and it is clipped half across the last character. Also note the way you code the testcase (probably due to the sequence of commands you used to compose the scene) won't start on mac. I reorder the code to: @Override public void start(Stage primaryStage) throws Exception { final Canvas canvas = new Canvas(120, 120); GraphicsContext _gc = canvas.getGraphicsContext2D(); // _gc.setLineWidth(1); _gc.setFont(new Font(30)); // _gc.setTextAlign(TextAlignment.CENTER); _gc.strokeText("Text2", 50, 60); Pane borderPane = new VBox(canvas); borderPane.setPrefSize(180, 190); borderPane.setStyle("-fx-border-color: darkgray;"); Group root = new Group(borderPane); primaryStage.setScene(new Scene(root, 300, 300)); primaryStage.show(); }
