TextArea and WebView controls render their content with a strange "blur" inside PopOver. TexField is sharp, other two controls are not:

Sample Code:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.TextArea;
import javafx.scene.control.TextField;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.StackPane;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
import org.controlsfx.control.PopOver;


public class PopoverBlurredApplication extends Application {
    public void start(Stage primaryStage) {

        final Button button = new Button("Press Me");
        StackPane root = new StackPane(button);

        final PopOver popOver = new PopOver();
        BorderPane popOverRoot = new BorderPane();
        TextArea textArea = new TextArea("Text in TextArea");
        TextField textField = new TextField("Text in TextField");
        WebView webView = new WebView();
        webView.getEngine().loadContent("<html>Text in WebView</html>");
        popOverRoot.setTop(textField);
        popOverRoot.setBottom(textArea);
        popOverRoot.setCenter(webView);
        popOver.setContentNode(popOverRoot);

        button.setOnAction(e -> popOver.show(button));

        Scene scene = new Scene(root, 200, 200);

        primaryStage.setScene(scene);
        primaryStage.show();
    }
}
