Java game loop (painting) freezes my window

Question

I\'m changing \"views\" with cardLayout (this class has a JFrame variable). When a user clicks a new game button this happens:

public class View

What does update do? You probably shouldnt call game.loop() on the EDT. You are running a loop on EDT, your repaint wont ever be invoked since repaint queues an event on EDT and it seems kind busy. Try moving game.loop() to another thread

new Thread(new Runnable() {
    @override
    public void run() {
        game.loop();
    }
}).start();

This way you wont block the EDT while the repaint still gets to be executed on the EDT.
