    Description

      It appears that commit 3b7db8ac90ba36949cb4168f07cc8dace47758a7 ( https://codereview.qt-project.org/#/c/257497/ ) has caused a serious performance regression in gradient painting.

       

      This is visible in QMLBench tests for Creation/Layouts.<< Performance graph>>

       

      Benchmark performance sees significant regression on all platforms:
      85% on windows
      50% on Mac
      ~10% Linux
      10-20% Linux on ARM
