Control is not displayed in Xamarin Community Toolkit TabView
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:
- Open the sample app(TestApp.Android).
- Click on 'Tab 2.'
- Click on 'Tab 1.'
- 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.
