Apple unveiled its latest-generation iPad mini last month and it instantly became the talk of the town. The tablet does not compromise on performance despite coming in a compact size. However, as buyers start receiving their pre-ordered units, some of them noticed a subtle 'jelly scrolling' issue with the display.
The issue is said to be noticeable while scrolling through any content like reading a book or browsing a web page on the display in portrait mode. There is a slight difference in refresh rates of the left and right sides of the panel where the latter appears to be refreshing faster. This results in a wobbly kind of effect as you scroll up or down. The issue has been spotted by a few Reddit users as well as Dieter Bohn of The Verge and folks over at Ars Technica.
Here is is slow-mo video of scrolling on the iPad Min i slowed down EVEN MORE in a frame-by-frame step through. Notice how the right moves up faster than the left.— Dieter Bohn (@backlon) September 22, 2021
In normal usage you barely see it, but every now and then it become noticeable. In landscape it goes away entirely pic.twitter.com/iq9LGJzsDI
In response, Apple has told the publication that it is normal behavior for an LCD display panel to show the jelly scroll effect. This is because these screens do refresh line by line, there is a tiny delay between when the lines at the top of the screen and lines at the bottom are refreshed. The statement essentially means that Apple does not consider it as an issue/bug that needs to be fixed.
It is important to note that the jelly scrolling issue is not significantly noticeable. It is very subtle and one will need to pay very close attention to the display as they scroll to be able to tell its existence. In other words, it is not something that should make you avoid the new iPad mini or reconsider your decision.
