The retina display seems to have a lag in the refresh rate, from the left to the right. In portrait mode, scroll up and down quickly, and horizontal lines become diagonal, with the right side trailing the left.
The same effect can be seen in landscape, but now it's lag is top to bottom.
It reminds me of the rolling shutter effect that makes vertical lines appear slanted when moving the camera quickly.
