That also happens in Chrome, not just Safari, and also in iOS 6, not just iOS 7. I think iOS 7 is hideous and garish, it's mostly about cosmetics fluff with little useful functionality added. Whatever useful functionality
has been added, could have been added as an incremental iOS 6 update, sparing the rest of us all this visual pain. The all-white keyboard looks especially ghastly in e-readers in night mode! The dock is fug-ugly, too, and let's not even mention the ridiculous new flat icons (was the Camera icon designed by a 5-year-old?; the new Settings icon makes me cringe).
Oh, and could there be anything uglier than the new Notes app? Naturally, I don't use it, because it's a dumb app like any other typical Apple app. (I use Nebulous Notes instead.) But who could ever have thought that opening an all-white empty sheet and typing in the excruciatingly vanilla Helvetica font could possibly be more impressive or elegant than the former very nice yellow pad and especially the
outstanding Noteworthy font? Being blinded with a huge slab of an all-white tablet screen (especially at night) is like being hit with a sledgehammer. It transforms the Notes app into a flashlight app. What a design disaster.
