    How to reproduce:

    1. Create an empty project on Unity 2021 or 2022.
    2. Build the project , then run it on iPhone14 and connect to Profiler.
    3. Press the mute/unmute button on the device, when the Dynamic-Island show, frame rate will drop to 30, after it disappear, frame rate will be back to 60.
    4. You will see the reason is FinishFrameRendering in Profiler.

    I tried it on Unity 2019 and change the graphics API to OpenGLES3, it works perfect.
    So I think the reason is Metal

    There's no chance for our project go back to Unity 2019, so any solution or advice will be very thankful !!!
