    Description

      Calling SetWindowDisplayAffinity() with any flag on a main window breaks the scene geometry.
      Relevant only for D3D11 RHI backend (default on Windows), not reproducible with OpenGL RHI.

       

      See simple demo project WindowAffinity.zip

      Steps to reproduce:
      1. Build and run sample project
      2. Push the button
      3. Observe the window

       

       

      Actual results: all Quick scene is shifted at the top left, visual artifacts, etc
      Expected results: no side effects
