Using version 21.1.299
In Layout when you view a scene that is based on a camera view not a section view and render mode is either Vector or Hybrid, the camera view is not displayed correctly. In both Hybrid and Vector mode all the objects display in a wireframe including the object behind the camera view. The camera view works in Raster mode.
If you use a section for the scene all the Render mode display correctly. Just started happening in the last version. Any ideas?
