I am helping someone diagnose an issue or maybe a feature? When their 2011 macbook air 13 inch boots from deep sleep (which is after a hour correct?) it will display the filevault login screen which doesnt have the normal canvas background and then it will also ask for the password again when it boots this time using the normal wake from sleep screen which displays the darkened desktop background. Is this normal behavior? Their screen also flashes slightly when waking from deep sleep like its initializing the screen. These behaviors don't happen in normal sleep like closing the lid and then opening it in less than an hour.
