      By scaling display settings, svg image is getting pixelated.

      Even adding following Image control to prevent it does not works when application starts and then display is scaled to 150% or higher on windows.
      sourceSize.width: rDDErrorImgWidth * Screen.devicePixelRatio
      sourceSize.height: rDDErrorImgHeight * Screen.devicePixelRatio

      Attached source code, image and screenshot of windows settings.
