Let's go with this. Ideally we would just flush once and for all
before we block again, but we're limited by the simple nature of
wl_display_run(). We could just not use that and open-code the loop,
and then emit a "pre-block" signal before we call
wl_event_loop_dispatch(display->loop, -1);
to let compositor-wayland.c flush it's pending requests before
blocking. But let's stick with the simpler solution here until we
come across something else that hits this problem.
