I've had the same problem with other functions (scrolling before mapping).
To be sure that the window is mapped, I've inserted the
following code.

Event e;

  window->map();
  window->display()->sync();
  while (!window->is_mapped()) {
    Session::instance()->read(e);
    e.handle();
  }

Event e;

  window->map();
  window->display()->sync();
  while (!window->is_mapped() || Session::pending()) {
    Session::instance()->read(e);
    e.handle();
  }

The bottom code works if I map the ApplicationWindow and the top one
work for the other windows, but I can't say why !?
