I see it often, and I hate it. It standardises on width, so everything that's wide (landscape oriented photos, or in this case desktop windows) gets shrunk dramatically. In this particular case, it makes the largest viewports look the smallest, and makes the smallest ones look largest. It's indeed very deceptive.
