In my bare bones understanding of gas laws, it's not the size of the window that is the problem, but the shape.
Am I wrong?

Not necessarily the shape, but it does limit the differential pressure. The Gulfstreams are proud of their huge oval windows, and they hold a pretty good dif. Then there is the Turbo Commanders with huge rectangle windows. I've never flown one, but it probably doesn't hold a big dif.
