Thank you for the description and screen shot demonstrating the issue you experience.

Forty Thieves is one of the most crowded layouts with two decks of cards, eight foundations, a stock and a waste pile across the top, followed by ten tableaus beneath.

With the screen shot showing that two columns of cards are covered/hidden on the right-hand-side, I think that moving the stock and waste pile will still leave many cards hidden by the mockup thumb.
