屏幕撕裂/滞后java

Question

好的，所以我看了无数线程试图找到解决方案，但还没找到。在我尝试使用Java进行的3场比赛中，我偶尔会遇到延迟/屏幕撕裂。当它发生时，我的FPS似乎是相同的，但它仍然滞后。这是我正在使用的游戏循环和渲染方法。

public void run() {
    long lastTime = System.nanoTime();
    double nsPerTick = 1000000000D / UPS;

    int frames = 0;
    int updates = 0;

    long lastTimer = System.currentTimeMillis();

    double delta = 0;

    while (running) {
        long now = System.nanoTime();
        delta += (now - lastTime) / nsPerTick;

        lastTime = now;

        while (delta >= 1) {
            update();
            updates++;
            delta--;
            render();
            frames++;
        }

        if (System.currentTimeMillis() - lastTimer >= 1000) {
            lastTimer += 1000;
            System.out.println("Frames: " + frames + " | Updates: " + updates);
            frames = 0;
            updates = 0;
        }
    }
}

public void render() {
    BufferStrategy bs = this.getBufferStrategy();
    if (bs == null) {
        this.createBufferStrategy(3);
        return;
    }

    do {

        do {

            Graphics g = bs.getDrawGraphics();
            Graphics2D g2 = (Graphics2D) g;
            g2.drawImage(canvas, 0, 0, screenSize.width + 10, screenSize.height + 10, null);
            g2.setColor(Color.WHITE);
            g2.fillRect(0, 0, screenSize.width, screenSize.height);
            if (getCurrentScreen() != null) {
                getCurrentScreen().render(g2);
            }

            Toolkit.getDefaultToolkit().sync();

            g.dispose();
        } while (bs.contentsRestored());
        bs.show();

    } while (bs.contentsLost());
}

有人对此有任何解决方案吗？谢谢！
