The code that gets the size already reads the ActualWidth and ActualHeight. If they are not defined then Width and Height are read.
DXSceneInitialized event is called from DXViewportView - in case WPF 3D rendering is used, then the DXScene is not be initialized. You can check that with DXViewportView.UsedGraphicsProfile. WPF 3D can be used as a fallback if there was an error during initialization.
Is it possible that you create a simple project and send it to my email so that I can reproduce your issues and can check that in more details. It is quiet hard to guess what could be the cause if I do not have enough information.
An event that is triggered before Update is DXViewportView.SceneUpdating.
