SDL_HINT_MAC_OPENGL_ASYNC_DISPATCH - A variable controlling whether dispatching OpenGL context updates

       This hint is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.20              SDL_HINT_MAC_OPENGL_ASYNC_DISPATCH(3)

       The variable can be set to the following values:

       • "0": Dispatching OpenGL context updates will  block  the  dispatching  thread  until  the  main  thread
       finishes processing. (default)

       • "1": Dispatching OpenGL context updates will allow the dispatching thread to continue execution.

       Generally you want the default, but if you have OpenGL code in a background thread on a Mac, and the main
       thread  hangs because it's waiting for that background thread, but that background thread is also hanging
       because it's waiting for the main thread to do an update, this might fix your issue.

       This hint can be set anytime.

       SDL_HINT_MAC_OPENGL_ASYNC_DISPATCH  -  A  variable controlling whether dispatching OpenGL context updates
       should block the dispatching thread until the main thread finishes processing on macOS.
