We have an issue with a special case where the DialogManager and ScreenView's as well as App Bar's graphics raycasters are resulting in input being swallowed by the ScreenView which leaves us with Dialog components that cannot be interacted with. In the interim we have found a quick fix is to disable the screen views graphics raycaster that gets injected in the Show method and then enable it again in the Hide method of the MaterialDialog base class, but this still leaves the App Bar broken.
