The iPad mini 6 may have an issue with the way the display refreshes when scrolling. One half of the screen appears to refresh faster than the other. This is colloquially called the "jelly" effect.
The iPad mini 6 introduced an updated display to the compact tablet design, but it still has some teething issues. Upon closer inspection, there appears to be a limited "jelly scrolling" issue with the tablet. As The Verge's Dieter Bohn reports on Twitter, the left and right sides of the screen update out of sync when the device is used in portrait orientation. The effect, which has occasionally occurred on devices in the past, is particularly noticeable in situations like pages of text or when large patterns scroll up and down across the entire screen.
iPad mini 6: A hardware or software problem?
A video was published, which shows the phenomenon when scrolling a web page, with the right page updating just a hair before the left. However, the video is in slow motion to illustrate the effect for demonstration purposes. According to Bohn, the effect is barely noticeable but occurs “every now and then”. Furthermore, the problem does not occur when the iPad mini is used in landscape mode, but only in portrait mode. While it is plausible that this could be a hardware issue with the display panel itself, it is also possible that Apple will develop a software-side fix for a future iPadOS update. Since Apple itself has not commented on this so far, we can only speculate at this point.
