[Regression] Window as a Transparent overlay fails when using DwmExtendFrameIntoClientArea in the 2019.1 versions



How to reproduce:
1. Open the user-submitted project ("") and open "Scene"
2. Build the project and run it
3. In the standalone Player observe the background around the Cube Object

Expected result: The background is transparent, displaying whatever window that is behind the standalone build
Actual result: The background is black and doesn't display any other windows behind it

Reproduced in: 2019.1.0a12,
Not reproducible in: 2018.3.1f1, 2017.4.17f1

  1. Resolution Note (fix version 2019.1.7f1):

    Note: The fix was to add a checkbox to player settings ("Use DXGI Flip Model Swapchain for D3D11") that makes the Standalone player use old (pre 2019.1) behaviour.

    Tautvydas-Zilys on the forums: "It looks like it got broken because DwmExtendFrameIntoClientArea function doesn't work with flip-model swapchains, and in 2019.1 we switched our D3D11 implementation to use flip-model swapchain because it is more performance and supports technologies like GSync and FreeSync."
