New iPad image "wobbles" when scrolling

Am I seeing things? Go to a web page with some horizontal lines and move the page up and down with your finger. Don't flick the page, just keep your finger on the screen and quickly move it up and down. The items on the age will appear to wobble slightly, almost like a wave. You can see this most clearly on horizontal lines.

I must be going crazy?

Boy, peeps are really stretching now.

Pretty soon there will be complaints the iPad needs electricity.

All iPads have done this to some degree.

It's not an optical illusion, interlacing, or you going crazy. All LCD displays do this. They don't update the entire panel at once, it's done line-by-line.

However, with most LCDs you don't have very fast moving objects (particularly vertical lines) scrolling horizontally by the screen.

With the iPad in portrait mode, as soon as you start scrolling, everything is moving "horizontally" on the panel which makes this effect really obvious. (I suspect the fact that it's higher resolution, and therefore has more lines to address, also contributes)

If you open up a large window on your computer and quickly move it from left to right, you should also see that the bottom edge drags behind the top of the screen. Depending on your screen size and resolution, how obvious this is will differ though.

Thank you to those of you who helped answer my question. I'm glad it's normal and I knew there had to be a reasonable explanation.

My iPad glows on the front side. The back is fine, but where the glass is, I can see lots of coloured light shining through. Is it just me?

No, you're not crazy! It's not an optical illusion. New ipad wobbles when scrolling. Probably it's due to the enormous number of pixel that the gpu must move on the retina display. It's not so bad but this is defintely a flaw. I have also an ipad 1 and doesn't wobbles.
