问题
I'm building a Windows 8 Metro App based on the Grid Application template. Everything was going smoothly until I tried to change the Theme and Background of the App.
I applied an Image Background to all 3 XAML Page's Grid. Also, I changed the Theme to "Light" in the Application Package Manifest, but it didn't do anything.
After searching I found a solution, setting RequestedTheme="Light" in the App.xaml
Now, I have a Light themed Application with the background I want, but every time I navigate to a diferente Page it has a black flicker. It seems the transition still has the Black Theme.
Is that the problem? How do I change that?
Thanks

In App.xaml.cs, set the background property of the app's root frame. You can do it in the overridden OnLaunch method, just before navigation to the initial page.
rootFrame.Background = new SolidColorBrush(Colors.White); //whatever color
