Blank screen when 'abusing' device rotation on iOS?

Hey i'm having a bug with (maybe) resize events with my app on iPhone 5 / iOS7 and simulator, the UI is adapting to any screen size ( different orientations )

I'm not doing anything fancy, UI is classic flash display list and it changes layout perfectly on resize event, or well, i thought it did until now!

The case where it doesnt work --> ***and ends up in a blank screen***, is if i fire a lot of device orientation changes *at the same time as the application launches*

( literally spamming it while the launch image is up )

I suspect a Flash Player bug here? cause if do the same thing afterwards, once the launch image is gone, the UI adapts perfectly

Anyone having the same problem? ( easy to test : just spam loads of orientation changes right after you launch your app, my bug reproduces both on simulator and real devices )

Thanks
