      Description

      Running something like benchmarks\auto\changes\changing_over_isolated_with_clip_rotated.qml with qmlbench shows that the rhi path is always slower, especially with Vulkan.

      There is a difference even when disabling clip: true from the test case, esp. when increasing the number of (unbatched) items in the scene from 1000 to something bigger.

      QTBUG-78620 and QTBUG-78862 should improve this.
