I think this is a problem that needs to be tackled at a higher level. The reason the PDF preview does not display a blank page is becuase it fails to generate a new one from the current source. When such failure occurs, the latest generated preview remains in the view. The question is, what we want to do when the preview cannot be generated. Hiding/blanking the page might not be the best idea, because the preview is updated periodically and the user might be just typing something (which may not be compilable) and in which case we do not want to hide the preview from him.

That's a very good point regarding situations where a user is typing something that may not be compilable.
