The modal view messes with the views of other view controllers upon dismissing

[genaks]

My view controller presenting the modal view controller has the top element with a top spacing of 20. After dismissing the modal view using the drag down gesture, the top spacing seems to be gone. And it looks to be gone not only for the base view controller in that tab (I am also using a tab bar controller), but it's also gone for other view controllers in the tab bar controller. Let me know if you want screenshots.

Something similar is happening to me, my tab bar (from my UITabBarController) is getting shifted like 100 pts up the screen from the bottom.

EDIT: when I change the behindViewScale to 1.0 it no longer happens, so it looks like there's an issue when transforming the presenting viewcontroller.
