    Description

      Bumped into strange performance issue and made a simple tester app for it. Running it and clicking the screen to turn BusyIndicator running makes on my system fps to drop 60 -> 30.

      Notes:

      • Happens only when View3D contains Texture with sourceItem.
      • And msaa is enabled using QQuick3D::idealSurfaceFormat(2). No matter is SceneEnvironment antialiasingMode MSAA or not.
      • And there is also some Quick controls 2 component which uses QQuickAnimatedNode. So e.g. BusyIndicator.

      So is this bug just in my windows system, in Quick3D. or Quick controls 2..?
