Calling function flushAndWait will always block on it if I not run it on main thread. Under the mac arm64 architecture. #8137

⚠️ Issues not using this template will be systematically closed.

Describe the bug I want to use off-screen rendering to do something. When developing on the Mac platform, for some reason, I must work on non-main thread . Then I found that if I render on a non-main thread, it will be blocked in flushAndWait，This happened to me on Mac(M1), but not on Windows.

To Reproduce Steps to reproduce the behavior: the code like this:

void test(){
//do init   engine , scene, render
....
//  do  begin frame ,   readpixel ,  endframe,  flushAndWait
renderer_->beginFrame(swapchain_);
 renderer_->readPixels(....);
renderer_->endFrame(swapchain_);
//block here
engine_.flushAndWait();

}

int main(){
    std::thread work(test); 
    work.detach()
    getchar();

    return 0;
}

Expected behavior hope can on non-main thread render image (on mac M1 arm64)

Screenshots no Logs no

Does this happen with the Metal backend too?

Does this happen with the Metal backend too?

Yes， I use the filament example hellotriangle.cpp, just run it on non-main thread, it cant work . the code like this:

int test3(int argc, char** argv);
int main(int argc, char** argv) {
     std::thread work(test3, argc, argv);
     work.detach();
     getchar();
     return 0;
}

int test3(int argc, char** argv) {
    App app{};
    app.config.title = "hellotriangle";
    handleCommandLineArguments(argc, argv, &app);
    app.config.backend = Engine::Backend::METAL;
.........
}

the error msg :
