iOS screen flashes while transitioning to screen with web browser component

[GoogleCodeExporter]

Relates to iOS device. Android and simulator do not show this behavior.

What steps will reproduce the problem?
1. Form with a webbrowser component not covering the full form.
2. Navigate from a dark form to the form with the webbrowser.

What is the expected output? What do you see instead?
Expected smooth transition. Instead the area occupied by the webbrowser flashes 
white before the transition starts.

What version of the product are you using? On what operating system?
Latest CN1 libraries (checked!) Device is iPad mini with iOS 7.1.2

Please provide any additional information below.
Only the area covered by the webbrowser flashes, hinting that the (native?) 
browser component is created on-screen.

Navigating back to the previous form appears to first remove the native browser 
component, and then start the animation. The result is another annoying screen 
flicker.

After some testing, I ended in the situation where the browser was removed, and 
the form was empty. The transition did not occur, leaving me with a frozen 
screen and non-responsive title bar.

After a while, the right half of the screen suddenly went black but was 
restored moments later. (Not sure if this is related, as I have observed this 
before in other forms.)

PS: I have configured ios.newPipeline=true
