多监视器JavaFX的显示问题

我的应用程序按预期运行，但运行时会出现显示问题。当它运行时，java窗口会弹出正确的窗口大小，但是由于某些原因，窗口中的控件非常大。我能够解决这个问题并让它们以正常大小显示的唯一方法是，我将窗口拖到另一个显示器上，将其放下（此时超大的控件会移动一点），然后将其拖回笔记本电脑显示器。然后控件收缩并正确显示

但是，如果我把它拖回到我的另一个监视器上，控件会再次爆炸

我使用的是运行在MacOSX 10.10.3上的IntelliJ 14和Scene Builder 2.0

FXML文件：

<?xml version="1.0" encoding="UTF-8"?>

         <GridPane.margin>
            <Insets />
         </GridPane.margin>
      </Button>
      <Label fx:id="lblTop" alignment="TOP_CENTER" contentDisplay="TOP" GridPane.halignment="CENTER" GridPane.rowIndex="1" GridPane.valignment="TOP">
         <GridPane.margin>
            <Insets top="35.0" />
         </GridPane.margin>
      </Label>
      <TextField fx:id="txtKey" alignment="CENTER" editable="false" GridPane.rowIndex="1" />
   </children>
</GridPane>

UPADATE：

这个问题似乎是一个智能问题。我决定尝试构建我的应用程序，在我运行JAR之后，它工作得非常好。应用程序的逻辑功能正常，上述显示问题不再出现

在监视器之间移动时，它确实会稍微调整大小抖动，但它从不错误地显示元素

package sample;

import javafx.event.ActionEvent;
import javafx.fxml.FXML;

import javafx.fxml.Initializable;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import java.beans.EventHandler;
import java.util.ResourceBundle;
import java.util.Random;
import java.awt.*;
import java.net.URL;



public class Controller implements Initializable{

    @FXML
    private TextField txtKey;
    @FXML
    private Label lblTop;
    @FXML
    private Button btnButton;

    Random rnd = new Random();
    private char[] pool = {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','0','1','2','3','4','5','6','7','8','9'};

    @Override
    public void initialize(URL fxmlFileLocation, ResourceBundle resources){
        assert btnButton != null : "fx:id=\"txtKey\" was not injected: check your FXML file 'sample.fxml'.";
    }


        public void foo (ActionEvent actionEvent){
            String key = "";

            for (int i = 0; i < 32; i++){
                key = key + pool[rnd.nextInt(36)];
            }

            lblTop.setText("Your Encryption Key is:");
            txtKey.setText(key);
    }

}

package sample;

import javafx.application.Application;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("Encryption Key Generator");
        primaryStage.setScene(new Scene(root, 300, 275));
        primaryStage.show();
    }


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