Not necessarily. As I reported in another message, one particular PDF I viewed with Okular did not render the thumbnail until it 
was scrolled into view.

But during rendering, even a timer object doesn't trigger, as the whole application seems to be caught up in the rendering. So showing the document first, gives some visible comfort to the user, but you can't do shit until the rendering is finished.

You could determine if the document has embedded thumbnails, when it is loaded, by testing if a thumbnail for the first page is 
found. If thumbnails are not embedded and self-rendering is needed, you could:

Load up a generic, lightweight thumbnail for each page and then use IconView's Draw event to render an appropriate thumbnail, or
Use Tasks to generate the thumbnails.
