The Sample Projects
When switching the MainPage (in App.cs) from a SplashPage (just a basic ContentPage) to a MasterDetail with a TabbedPage with a single child ContentPage a blank/grey screen is shown for a short amount of time before the TabbedPage's child page is shown. This is more noticeable on lower end devices, and when more content is added to the ContentPage within the TabbedPage. This issue, however, does not occur in Xamarin.Forms 2.0.1 (default when creating a new project in XS). Once I updated to 2.3.2, however, it does. I've included two projects that are identical except for the version of Xamarin.Forms they're using; 2.0.1 and 2.3.2.
Should be fixed in 2.3.3-pre3. Thank you!
I have checked this issue with Xamarin.Forms 2.3.3-pre3 and observed this issue has been fixed.
Hence closing this issue.
