[Bug] UWP app doesn't update page layout after window resize #14498

Open rettiseert opened 3 years ago

rettiseert commented 3 years ago

Description

I've found that if I resize the window, the active page resizes its elements fine, but an inactive previously visited page doesn't. The inactive page retains the same layout as before the window resize.

Steps to Reproduce

  1. Create a new Xamarin Forms UWP app with a flayout template in Visual Studio 2019.
  2. Run the project.
  3. Navigate to "Browse" page.
  4. Resize the window.
  5. Go back to "About" page. It shows an incorrect layout, as if window had the same size as before.
  6. Resize the window again, then "About" page finally adjusts its elements size and layout.

Expected Behavior

Previously visited pages should show a correct layout even if window size changed.

Actual Behavior

Previously visited pages show an incorrect layout if window size changed.

This is a duplicate of #12936. It is a very annoying issue. Let us hope that our Windows users do not resize the window too often :-).

Hi,

Any news about this problem?

I have tried several things to try to render the page again in OnAppearing, but nothing works (Layout, ForceLayout, InvalidateMeasure).

Is there any workaround to solve this?

Thanks!
