[Bug] [iOS] ShadowEffect disappearing when coming back to the app (only with the Frame view)

[lartisanetsonmobile-admin]

Description

I have added a shadow effect to a Frame

<Frame WidthRequest="200" HeightRequest="100" xct:ShadowEffect.Color="Red" xct:ShadowEffect.OffsetY="5" xct:ShadowEffect.Radius="10" CornerRadius="10" HorizontalOptions="Center" BackgroundColor="Gray"/>

The shadow effect is disappearing when coming back to the app.
This issue exists only on iOS and only with the Frame view.

Steps to Reproduce

1. Create a blank Xamarin.Forms application.
2. Add XCT package.
3. Add the Frame above to the MainPage.xaml
4. Launch the app on iOS Simulator/Real device
5. Put it on the background
6. Return to it

Expected Behavior

The shadow is not disappearing

Actual Behavior

The shadow is disappearing

Basic Information

• Version with issue: 1.3.0
• Last known good version: Unknown
• IDE: Visual Studio 2019 Mac
• Platform Target Frameworks:
  • iOS: Tested on 14.1 and 15

@lartisanetsonmobile-admin are you having the same issue with other layout then frame like for StackLayout. As Frame has it's own shadow that might be interfering with shadow effect

[lartisanetsonmobile-admin]

@SarthakGz No, only with Frame layout. It works fine with StackLayout, Grid, Button etc.. But i use Frame because it has the CornerRadius property.
Yes, It is probably interfering with the Frame's default shadow

[SarthakGz]

@lartisanetsonmobile-admin For corner radius you can use CornerRadius effect provided by XCT or Clipping api by Xamarin forms you can apply that on any Layout for now at-least as a workaround or try HasShadow=false for Frame

[lartisanetsonmobile-admin]

@SarthakGz I will try this workaround, thank you for helping :)

[lartisanetsonmobile-admin]

@SarthakGz I can't find any CornerRadius effect in XCT. And i think the ShadowEffect is overriding corner radius effects on Android

@lartisanetsonmobile-admin check this PR I think this is merged though couldn't find it either

That PR has been merged but it's currently only on the develop branch which means it hasn't officially been released yet.

@lartisanetsonmobile-admin did you ever find a solution or workaround for this? I'm experiencing the same issue on XCT 2.0.0.
