Xamarin.forms: Flicker in Master Detail Navigation

[steven-pearson]

Bug report best practices: https://github.com/xamarin/Xamarin.Forms/wiki/Submitting-Issues

Description

White screen flickers within the transition from page to page in the PushAsync when navigating (as if a whole white screen is painted between the transitions). Previous versions were smooth.

Was ok in 2.3.4.270 can confirm present in 2.5.0.121934 (but may be since 2.4.x as reported by others)

Steps to Reproduce

To recreate=> Create a simple master detail app and add a few pages to switch between (can be the same page)
Navigate between the pages and notice a very quick white screen flicker between them.

Revert XF back to 2.3.4.270 and try again. No white screen

Problem becomes more exaserbated when page content is more complex (white screen is shown longer).

Expected Behavior

Clean transition

Actual Behavior

Flicker's background mid transition

The problem still persists (XF 2.5.0.280555) and becomes more and more annoying :-(

Same problem here

[CSeb96]

A workaround I did was:

var page = new Page();
var masterdetail = new YourMasterPage() {Detail = new NavigationPage(page) };
await Navigation.PushAsync(masterdetail);

No more flickering between pages for me.

Even in version 2.3.4.270 the problem happens

I've just posted a solution that may help.

What's the hold up on this issue? These kind of cosmetic problems just make the Android apps built with Forms look bush league. The workaround by @PMarsh-UB kind of works, but it's the exact opposite how the official Xamarin documentation says to use the master/detail page. When I tried it, the title stopped getting picked automatically from the detail page, and the nav drawer icon disappeared, so thats nice...

I guess it's all we can expect, considering how unusable Forms 2.5 and greater is, this is low hanging fruit.

Is there any news or progress on this bug?
