Solution to reproduce error
When presenting a modal view controller using FlipHorizontal transition style and FormSheet presentation style, the modal view is first displayed and then animated. It should animate first, as it used to in classic api.
Provided is a demo solution to reproduce the issue. Steps to reproduce
1. Press Red Button
2. Observe how modal view is quickly presented THEN flipped. This is not correct.
I also suspect other transition styles may contain visual anomalies.
Below are my environment details.

NOTE: this is being tested on iPad Simulator and iPad devices.
This is what I see: http://screencast.com/t/NhvTskVz
I also get the exact same behaviour from an equivalent Xcode app: https://github.com/rolfbjarne/bug29111, so it doesn't look like an issue in Xamarin.iOS (I tried a Classic app as well, and the behaviour is the same there too).
So can you attach your Classic project as well so I can see where the difference is?
When I referred to Classic app, I meant the actual app I'm developing.
This bug, in the equivalent classic solution, also occurs, so it may be one of the other changes made in 8.8.0 or maybe iOS 8.3 API. I'm not really sure, I just know it's not supposed to look that way.
I just tried the Xcode sample in older simulators, and there's a difference in the iOS 7.1 simulator, while the 8.1, 8.2 and 8.3 simulators all behave the same, so this looks like an iOS bug/difference in iOS 8.0+
I'm closing this since it's not an issue with Xamarin.iOS.
Are you able to provide a downloadable copy of your screencast so that I can lodge this bug report with Apple?
