This sounds like an issue in your myDisplaySink plugin? You can
implement the GstBaseSink::unlock vfunc to make your render function
(which is in another thread than the state change) return (with a

Why does that concern you? playbin creates the pipeline dynamically when
starting playback, so when starting up it has to start up elements in a
different order. State changes go from sinks to sources, as far as those
are in the pipeline already, that is normal (see the design docs).
This should not make any difference to your plugins.
