Controls not refreshed properly when resizing the window.

Hi Team,

When I am trying to resize the window, Xamarin controls are blinked. I want to update the controls smoothly when resizing the window.

Please find the attached sample to reproduce the problem.

Replication procedures:

* Click any button in the Page1 page and then slowly resize the window using the resizable cursor. Now the “Click” button blinked continuously.

Is any other way to smoothly update the controls when resizing the window?

I can see the behavior you are describing with the attached project. It looks like the navigation animation runs every time the window is resized which makes the page content flash. I'm confirming the report so the team can investigate further.

### Version tests    BAD
2.3.5-pre3  BAD   BAD

This is a result of the animation type being used. See: https://github.com/xamarin/Xamarin.Forms/pull/926

Should be fixed on 2.3.6-pre1
