[Qt 3D] QSG_RHI_BACKEND : d3d11 produces unexpected results

XMLWordPrintable

    • Windows

      Objects are drawn fine with QSG_RHI_BACKEND: opengl.
      However, the same code with "d3d11" produces a different result (wrong aspect ratio, no lines) and the error message below. 

      Failed to create input layout: Error 0x80070057: ???????????????
Qt3D.Renderer.RHI.Backend: Failed to build graphics pipeline: Creation Failed

      opegl

      d3d11

      The sample code Qtbug106082.zip is attached.
      Build and run.
      Switch between opengl/d3d11 in main.cpp.
