Switching rootViewController with MMDrawerController: weird behaviour of the transition animation

Question

I'm switching the rootViewController of the AppDelegate's window at some point of the app lifecycle. I'm trying to animate such switch this way:

[UIView transitionFromView:self.window.rootViewController.view
                    toView:self.otherViewController.view
                  duration:0.65f
                   options:UIViewAnimationOptionTransitionFlipFromRight
                completion:^(BOOL finished){
                    self.window.rootViewController = self.otherViewController;
                }];

Animation is performed but it looks like the second view's height does not fill the screen height, and it suddenly fits the whole screen height once the animation has finished. I hope I've explained properly... what could be happening?

Thanks

EDIT: I've noticed this behavior appears when self.otherViewController.view is a MMDrawerController. I tested the code transitioning from a UINavigationController to another UINavigationController and nothing strange is shown... Has anybody experienced this?
