Screen gets cut and hangs for few seconds upon rotation

Question

My windows 8 store xaml app gets cut in half upon rotation from landscape mode to Portrait mode and vice versa. Upon rotation the screen gets hanged for a second and gets cut. After a pause of around 3 seconds it gets adjusted to portrait mode. To get the app adjust in portrait mode i have written a storyboard that resizes the buttons and other columns.Then we are calling this storyboard or viewstate on size changed event. We have noticed that many Microsoft apps like mail, people, news apps has the same behaviour. Is there any way to fix this? Or does all the apps on Surface take time to re-adjust? Any reason for this? How can I fix it? Please check the screen shot taken at the time of rotation.. 

Answer 1

I don't do much in the way of rotation, so I haven't noticed this. However, it sounds like you're describing an OS-level issue rather than an app issue. But that said, if you were to have content down in the area that is off-screen in landscape mode but would be on-screen in portrait, does it show up or is it just blank?

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.

Answer 2

Are you doing any kind of complex operations in the "WindowSizeChanged" event handler? This might happened because of complex implementation for handling view of app in landscape or portrait, as all those operation will be executed on the UI thread.
