SKGLView exception when ViewExtensions.RotateYTo called on parent view [Xamarin Forms UWP]

[comfr3ak]

Description

When ViewExtensions.RotateYTo is called on the parent view (like a Grid) of an SKGLView, an unhandled exception occurs:

System.Exception: Failed to create EGL surface
at SkiaSharp.Views.GlesInterop.GlesContext.CreateSurface(SwapChainPanel panel, Nullable1 renderSurfaceSize, Nullable1 resolutionScale)
at SkiaSharp.Views.UWP.AngleSwapChainPanel.EnsureRenderSurface()
at SkiaSharp.Views.UWP.AngleSwapChainPanel.OnCompositionChanged(SwapChainPanel sender, Object args)

Code

Create a window with a Grid. Add a SKGLView object to the grid. Then perform the following call on the grid object several times from 180 to 0, leaving plenty of time in between. It will crash, usually on the first try:

Xamarin.Forms.ViewExtensions.RotateYTo(<Your Grid Object>, 180, 300);

Expected Behavior

The parent view should flip horizontally without crashing.

Actual Behavior

The parent view flips partially, then the application closes with the exception. Sometimes it succeeds but always crashes within a few tries.

Hi,
Has anyone looked into this bug @mattleibow? I think I'm hitting the same issue with a simple Navigation action between pages containing the gl view.

I opened #1573 in case it was a distinct root cause, and to provide more details.
