Android 13中Fragment内GlSurfaceView恢复时UI冻结问题求助

我有两个均包含GLSurfaceView的Fragment：第一个Fragment的按钮可导航至第二个Fragment，第二个Fragment的按钮可返回第一个。两者的GLSurfaceView使用同一种Renderer，该Renderer仅实现背景颜色渐变功能。

异常表现 #

• 处于第二个Fragment时，切换到其他应用再切回，整个UI会冻结；但第一个Fragment无此问题，尽管两者逻辑几乎完全一致。
• 该问题**仅在Android 13（SDK 33）**中出现，Android 12和14可正常运行。

触发条件 #

• Renderer每帧执行50万次gl.glClearColor操作时才会触发；若仅执行1次则无问题。
• 通过带动画的Fragment导航进入第二个Fragment时才会触发；无动画导航则正常运行。

代码实现 #

Renderer代码 #

public final class OpenGLRenderer implements Renderer
{
    public void onSurfaceCreated(GL10 gl, EGLConfig config)
    {
    }

    public void onSurfaceChanged(GL10 gl, int w, int h) {
        gl.glViewport(0, 0, w, h);
    }

    float color = 0.2f;

    public void onDrawFrame(GL10 gl) {
        gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT);

        color += 0.01f;

        if (color > 0.7) {
            color = 0.02f;
        }

        for(int i = 0; i < 500000; i++) {
            gl.glClearColor(color * 0.8f, 0.0f, color, 1.0f);
        }
    }
}

第一个Fragment代码 #

public class FirstFragment extends Fragment {

    private FragmentFirstBinding binding;

    @Override
    public View onCreateView(
            LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState
    ) {
        binding = FragmentFirstBinding.inflate(inflater, container, false);

        return binding.getRoot();
    }

    public void onViewCreated(@NonNull View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        binding.OpenGlGameGraphics.setRenderer(new OpenGLRenderer());

        binding.buttonFirstWithAnimation.setOnClickListener(view1 -> {
            FragmentManager manager = getParentFragmentManager();

            FragmentTransaction ft = manager.beginTransaction();
            ft.replace(R.id.FragmentMain, new SecondFragment());
            ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
            ft.addToBackStack(null);

            ft.commit();
        });

        binding.buttonFirstNoAnimation.setOnClickListener(view1 -> {
            FragmentManager manager = getParentFragmentManager();

            FragmentTransaction ft = manager.beginTransaction();
            ft.replace(R.id.FragmentMain, new SecondFragment());
            ft.addToBackStack(null);

            ft.commit();
        });
    }

    @Override
    public void onResume()
    {
        super.onResume();

        binding.OpenGlGameGraphics.onResume();
    }

    @Override
    public void onPause()
    {
        super.onPause();

        binding.OpenGlGameGraphics.onPause();
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        binding = null;
    }
}

第二个Fragment代码 #

public class SecondFragment extends Fragment {

    private FragmentSecondBinding binding;

    @Override
    public View onCreateView(
            LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState
    ) {

        binding = FragmentSecondBinding.inflate(inflater, container, false);

        return binding.getRoot();

    }

    public void onViewCreated(@NonNull View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        binding.OpenGlGameGraphics.setRenderer(new OpenGLRenderer());

        binding.buttonSecond.setOnClickListener(view1 -> {
            FragmentManager manager = getParentFragmentManager();
            manager.popBackStack();
        });
    }

    @Override
    public void onResume()
    {
        super.onResume();

        binding.OpenGlGameGraphics.onResume();
    }

    @Override
    public void onPause()
    {
        super.onPause();

        binding.OpenGlGameGraphics.onPause();
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        binding = null;
    }
}
