If you create a simple webview and display any web page in it scrolling to the right or left will cause the rendering to be corrupt.

Use a touch device and pan around or use your middle mouse button on the desktop and make sure you can make the scrollbar go left and right. On a touch device this makes the Webview unusable for pages that are wider than the view.

Example code to replicate this:

<code>

package sample;

import javafx.application.Application;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
import javafx.scene.web.WebView;
import javafx.stage.Stage;

public class Demo extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {

        Parent root = new BorderPane();
        primaryStage.setTitle("WebView Test");
        primaryStage.setScene(new Scene(root, 500, 500));

        BorderPane borderPane = (BorderPane) root;
        final WebView webView = new WebView();
        borderPane.setCenter(webView);
        webView.getEngine().load("https://www.google.co.uk/search?q=test");

        primaryStage.show();
        webView.getEngine().setJavaScriptEnabled(true);

    }


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