      Description

      It's a scene with few cylinders. Every cylinder uses the Qt3DRender::QLevelOfDetail class with the DistanceToCameraThreashold to switch between three Meshes of decreasing details. When moving the camera around, I would expect the cylinders around the camera viewcenter and between the camera position and the viewcenter to be updated. But as you can see in the video, that's not the case. Instead it's some how dependent from which side the camera is looking at the cylinders:
