    Description

      Run Qt6 multieffect testbed. Change blur amount to 1.0 and blur max to 64.

      • With d3d11 and vulkan backends the output looks very blurred as expected.
      • With opengl backend the output looks much less blurred & more pixelated.

      See the attached screenshots. I'm running it on windows laptop with 4k screen so could this be device pixel ratio related issue?
