The iFixit team has now taken a look at the new iPad mini 6 and explained the “Jelly Scroll” problem in more detail in a teardown video.
Some owners of the new iPad mini 6 have noticed that text or images on one side of the screen are tilted downward when scrolling through content. This affects all LCD screens, but is particularly pronounced on the iPad mini. According to iFixit, jelly scrolling is not usually as noticeable as on Apple's new 8.3-inch tablet and is caused by the way the screen refreshes. The screen refreshes in a wave-like pattern from side to side rather than all at once. On the iPad mini, iFixit suspects that the direction in which the screen is scanned is related to the placement of the control board that drives the iPad mini's display. For this reason, the jelly scroll issue is said to occur in portrait mode, but not on the iPad Air 4.
If you scroll parallel to the direction the display is updating, the display still won't update at the same time, but the effect of the update is less noticeable because the text isn't split. So you probably won't notice it on other screens. Jelly scrolling is usually obscured because the screen is updated (or scanned) parallel to the direction the scrolling motion is taking place. So a computer monitor will update vertically in landscape orientation, and a smartphone will update in portrait orientation. Coincidentally, the iPad mini's display will update horizontally if you hold it in the vertical orientation, which is how you normally hold the iPad for scrolling.
iPad mini 6: Apple has once again used too much glue
According to iFixit, it is also possible that Apple used a cheaper display panel for the iPad mini 6, which could have caused the refresh scan to be more pronounced than expected. Apple itself has already explainedthat the jelly scrolling problem is a normal behavior of an LCD display. This probably means that the company does not plan to offer a replacement device to users who have this problem. So if it bothers you, you should return the device within the return period and maybe get an iPad Air 4 instead. There were no other surprises with the iPad mini 6.
