To reproduce (convoluted, I know):

  1. Add params->server_side_decorated = true; to WindowWlSurfaceRole::create_scene_surface() to force server side decorations on Wayland apps
  2. Run weston-transformed (which has no cursor)
  3. grab an SSD resize edge and resize rapidly

Expected: it works

Actual: it crashes after a while with

ERROR: /home/wmww/code/mir/src/server/scene/surface_stack.cpp(248): Throw in function virtual void mir::scene::SurfaceStack::remove_input_visualization(const std::weak_ptr<mg::Renderable> &)
Dynamic exception type: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::runtime_error> >
std::exception::what: Attempt to remove an overlay which was never added or which has been previously removed

I suspect the problem has to do with insuficient locking in mg::SoftwareCursor::hide()

1348: Safely show and hide software cursor r=AlanGriffiths a=wmww

Fixes #1347 

1355: Enable `--display-config` for Mir-on-X r=wmww a=AlanGriffiths

Enable `--display-config` for Mir-on-X. (Fixes: #1326)

Note: if you test, using "--display config clone" with this exposes the race that #1354 addresses.
