Control is not displayed in Xamarin Community Toolkit TabView

[VolodaUa]

Something is wrong when the color picker is child element of TabViewItem(control -> Xamarin Community Toolkit TabView).
https://docs.microsoft.com/en-us/xamarin/community-toolkit/views/tabview

The color picker becomes transparent, but the color selection is still available.
You can swipe and see the selected color is changing.
I attached the sample which shows the issue.

Steps to reproduce the behavior:

1. Open the sample app(TestApp.Android).
2. Click on 'Tab 2.'
3. Click on 'Tab 1.'
4. See error

Expected behavior
The Color picker must be visible and displayed.

Information

• Device: Samsung m51, any emulator
• OS: Android only, iOS works well
• Version: 1.3.4.21, XF: 5.0

The workaround was found.
I found that the control uses SKGLView for drawing on Android.
Replacing to SKCanvasView helped to fix the issue.
iOS uses it and it works well. The same I can tell about Android. Performance issues weren't found.

@vpapenko Could you please tell me did you had some specific reason to use SKGLView on Android?
I found that there is a difference in rendering - SKCanvasView - CPU, SKGLView - GPU.

Hi @VolodaUa
Thank you for your investigation.
I started to use different SK Views because of optimization for the UWP platform.
Give me some time to check these changes and test your solution.
