----------
What does this mean ..
It seems like there's something wrong then, because the grid is loaded. These are resizing events after the window is built and when I'm already rendering.
onecoreuap\windows\wgi\winrt\display\displaycommon.cpp(411)\Windows.Graphics.dll!00007FFC79C804B0: (caller: 00007FFC79C801F5) ReturnHr(1) tid(2318) 80070490 Element not found.
The app at this stage is a simple UWP/Xaml/SharpDX app that does some raytracing.
Here's output showing it trigger on window resizing ..
