This means we cannot access [view layer] or view.bounds from the OpenGL thread. This also means that we need to call the main thread when setting the window handle. However, we cannot perform that synchronously as that may deadlock with the application performing the set_window_handle() call. We need to defer the actual update and run it asynchronously and wait for the window handle update internally at each point it is needed. Fixes: https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/issues/372 Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/merge_requests/681>
