Bug appears to be in: 
Javafx Version: 14.0.1+1 (Gluon)
Java JDK Version: 14.0.1+7
as well as :
Javafx Version: 8.0.241-b07
Java Runtime Version: 1.8.0_241-b07

A DESCRIPTION OF THE PROBLEM :
Using an ImageView to display an image, the picture appears blurry. 
Even "setPreservation" or "setCache" oes not help


REGRESSION : Last worked in version 14.0.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. create an Image class and load a image into it
2. create an ImageView class and stuff the image into it
3. pass the imageView to a container (stackPane,pane, VBox, etc)
4. create a scene and pass the container into the scene
5. pass the scene into the primaryStage and run the program

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The image will be displayed sharply in the correct dimensions
ACTUAL -
The image appears blurry in the correct dimensions

        System.out.println("Java Open JDK Version: " + System.getProperty("java.runtime.version"));

        ImageView imv = new ImageView();
        Image image = new Image(getClass().getResourceAsStream("xcode.png"));
        imv.setImage(image);
       // imv.setPreserveRatio(true);
      // imv.setSmooth(true);
       // imv.setCache(true);

        Pane root = new Pane();
        root.setStyle("-fx-background-color: black;");
        root.getChildren().add(imv);

        Scene scene = new Scene(root);

        primaryStage.setTitle("ImageView Blur");
        primaryStage.setScene(scene);
        primaryStage.show();

    }

    public static void main(String[] args) {
        launch(args);
