我是Java Game Programming的新手，我的游戏遇到了麻烦。我正在学校上课，为了好玩，所以我将代码从我学校的电脑和家里的电脑上传下来。
最近，当我在家里运行我的程序时，窗口闪烁得非常快，我不知道发生了什么。我使用缓冲策略并测试了一些值而没有任何变化。当我在学校计算机上运行代码时，运行正常。
我想知道我的问题实际上是缓冲策略还是我的Nvidia显卡正在为我的显示器做些什么。
我还录制了显示“闪烁”的屏幕，以便您可以在 this YouTube video 中看到我在说什么。
这是我的Game类使用缓冲策略。

public int width, height;

this.title = title;
this.width = width;
this.height = height;
keyManager = new KeyManager();
}

display = new Display(title, width, height);
display.getFrame().addKeyListener(keyManager);
