      Description

      When I have a simple animation of a circle moving across the screen I get "jerks" about every 0.5 seconds.

      Here is the code:

      import javafx.animation.Interpolator;
      import javafx.animation.TranslateTransition;
      import javafx.application.Application;
      import javafx.scene.Group;
      import javafx.scene.Scene;
      import javafx.scene.paint.Color;
      import javafx.scene.shape.Circle;
      import javafx.stage.Stage;
      import javafx.util.Duration;
       
      public class SmoothMovementTest extends Application {
          @Override
          public void start(Stage stage) throws Exception {
              Group root = new Group();
              Scene scene = new Scene(root, 800, 400, Color.WHITE);
              stage.setScene(scene);
       
              Circle circle = new Circle(50.0, Color.RED);
              circle.setCenterX(50.0);
              circle.setCenterY(200.0);
              root.getChildren().add(circle);
       
              TranslateTransition transition = new TranslateTransition(new Duration(5000.0), circle);
              transition.setToX(700.0);
              transition.setAutoReverse(true);
              transition.setCycleCount(10);
              transition.setInterpolator(Interpolator.LINEAR);
       
              stage.setVisible(true);
       
              transition.playFromStart();
          }
       
          public static void main(String[] args) {
              Application.launch(args);
          }
      }

      and here is some debug info:
