    Description

      ShaderEffectSource when applied changes the source image so that pixel-level shaders can't be applied.
      In the attached example there is an image with Bayer pattern. Run the application - the image is correctly shown. Uncomment the ShaderEffectSource. The expected result is that the image should stay unchanged, but no bayer pattern visible anymore.

      UPD: could be the same issue as here https://bugreports.qt.io/browse/QTBUG-107691
