Hi, There's a bug whenever using a ToolBar on Windows if you set your resolution scale > 100% (which is quite common). E.g., 125%:
[image: image.png] E.g., this is what a ToolBar always renders if scale is 125%: [image: image.png] As compared to what you'd expect (scale set to normal/100%): [image: image.png] Very easy to reproduce the above, set your scale to 125% and run this: public class ToolbarBugApp extends Application { @Override public void start(Stage primaryStage) { BorderPane bp = new BorderPane(); // Wrapping in HBox and using button with 13+ chars causes bug bp.setTop(new HBox(new ToolBar(new Button("Create Schema")))); // BUG // bp.setTop(new ToolBar(new Button("Create Schema"))); // NO BUG (no HBox) // bp.setTop(new HBox(new ToolBar(new Button("Create Schem")))); // NO BUG (12 chars) primaryStage.setScene(new Scene(bp, 600, 400)); primaryStage.show(); } public static void main(String[] args) { launch(args); } } As per the comments, this bug appears to happen when your ToolBar is wrapped in a HBox and contains a Button that has 13+ characters, for example. This is quite a serious bug, in my opinion. I believe this is present in JFX 24 and the JFX 25 master branch.
