Is it only diagonally? I ask because I've noticed it times on tumblr but just always figured it's slow response of the page loading. And with the additional length of the 5 it's loading quite a bit more with each scroll.
Do you actually have a source for this? Because your post doesn't make sense considering that it doesn't happen on the iPhone 4S, which is a dual core system.
I’m a developer, had experience with similar issue, which led to detailed examination on how scrolling works on iPhone. You can’t see it on iPhone 4S in Mail, or other app which is idling when you scroll, but if an app performs some task on main thread (or a task that constantly syncs with main thread) then you likely to get this syncing issue on any iPhone. And this is, indeed, a thread syncing issue by all accounts: main thread is responsible for both animation and user input, so when you get neither (on video scrolling stops and input is ignored) but the app is still running (after a whille scrolling will be unstuck).
In my case, that was fixable within the app. In this case it can be fixed like all thread syncing issues in generic UI component: with iOS update. My guess the culprit here is the higher frame rate on iPhone 5 (If iOS will set it to lower value for scrolling that would be enough) or similar trick, which can be done in an app. Of course, there are proper ways to fix it too. And, there’s a chance it is app-specific, and not every scrolling app affected.
Perhaps I’m not very good at explaining stuff, but still, it should be obvious from what I said above that it has nothing to do with hardware. Think of hardware touch input as of a camera that takes frame every set period of time. If you move finger too quickly before the lens it may not end up on any picture, but that’s all. So, if you are swiping and tapping fingers with superhuman (or monkey) speed some of it will be ignored by the hardware, but it’ll pass the rest of the input to the software, which will interpret it on a higher level.

See I'm a developer too, with a very low tolerance for bullshit, and your explanation does not address the fact that in the video it happened consistently on both iPhone 5s units but not on either of the iPhone 4Ses, and if you don't have a source for this other than being a developer, I'm sorry to tell you, but your guess here is as valid as anyone else's.

Both iPhones display at 60fps, and the frame rate can't affect anything since the rendering is composite, not to mention that no other animations were playing.

A developer? Google up UITrackingRunLoopMode and you’ll get the idea what I’m talking about.
This is not a new complaint for an Apple product. My MB 2007 has always gone sporadic scroll crazy and no amount of complaining, checking, fixing or update has ever fixed it. Worst computer I have ever owned from Apple. You don't learn to live with it, you just suffer the unpredictable.
I can on the latest update. To me it looks like an intentional circuit breaker response to overload input.
I too noticed this issue with my iPhone 5 when scrolling rapidly through emails, etc. However, after upgrading to 6.0.2 the problem seems to have gone away.

I get this same issue, but it doesn't have to be diagonal, normal quick swiping up and down on my music list also causes it to become unresponsive.

Hope, it explains things.

I understand what you're talking about; what I don't understand is why it should have any more credit than anyone else's guess.
