The text for the Axis in a LineChart does not render sometimes. Especially visible when resizing the application.

Reproducer, just resize the window:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.chart.LineChart;
import javafx.scene.chart.NumberAxis;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class LineChartBug {

    public static void main(String[] args) {
        Application.launch(FxApp.class, args);
    }

    public static class FxApp extends Application {

        @Override
        public void start(Stage primaryStage) {
            BorderPane root = new BorderPane();

            NumberAxis xAxis = new NumberAxis();
            NumberAxis yAxis = new NumberAxis();
            LineChart<Number, Number> lineChart = new LineChart<>(xAxis, yAxis);

            StackPane stackPane = new StackPane(lineChart);
            stackPane.setMaxSize(300, 300);

            root.setCenter(stackPane);

            Scene scene = new Scene(root, 1280, 540);
            primaryStage.setScene(scene);
            primaryStage.show();
        }
    }

}
