JavaFX TreeTableView rows gone when scrolling

I have been experimenting with the TreeTableView in JDK 8. After getting my program up and functioning, I noticed a problem that when I scrolled, rows would be getting blanked out. I have tried everything from resetting the visibility of the cell, when it updates, in hopes that it would redraw when it gets updated, or even resetting the visibility of the column. Here is a test applet I wrote to show that when you scroll for a tree table view, the rows get blanked out, but for a table view, this is not the case.

public class TableViewTest extends Application{

private TreeTableView treeTable = new TreeTableView();
private TableView regularTable = new TableView();

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

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

    final ObservableList<Person> data = FXCollections.observableArrayList(
            new Person("Jacob", "Smith", "jacob.smith@example.com"),
            new Person("Isabella", "Johnson", "isabella.johnson@example.com"),
            new Person("Ethan", "Williams", "ethan.williams@example.com"),
            new Person("Emma", "Jones", "emma.jones@example.com"),
            new Person("Michael", "Brown", "michael.brown@example.com"),
            new Person("Jacob", "Smith", "jacob.smith@example.com"),
            new Person("Isabella", "Johnson", "isabella.johnson@example.com"),
            new Person("Ethan", "Williams", "ethan.williams@example.com"),
            new Person("Emma", "Jones", "emma.jones@example.com"),
            new Person("Michael", "Brown", "michael.brown@example.com"),
            new Person("Jacob", "Smith", "jacob.smith@example.com"),
            new Person("Isabella", "Johnson", "isabella.johnson@example.com"),

        );

}

Does anybody know a fix / solution for this, or is this a known bug with the TreeTableView ?

EDIT: I just tried this using this example

https://wikis.oracle.com/display/OpenJDK/TreeTableView+API+Examples

and I still get the same issue of rows missing / being whited out.

Thanks to @Alexander Kirov for the solution. Upgrading to build 104 solved this issue.
