The recently released Moto Z2 Force could be suffering from the same issue as the OnePlus 5. It's not a particularly performance-breaking snag, to be sure, but it certainly looks annoying the more you notice it.
This is the so-called jelly scrolling issue, referring to the weird visual effect users see when they scroll through a list vertically. Like its name suggests, it looks as if it's jelly bobbing up and down with certain visual elements rubber-banding up and down abnormally.
Jelly Scrolling Cause
An inverted display causes the effect. In normally mounted displays, content refreshes from top to bottom. In inverted displays, it's in reverse. You can probably replicate the effect by turning your phone upside down and scrolling through a list, but this might not always work.
The folks over at XDA Developers were the first to discover the issue on the Moto Z2 Force, posting a video showing the effect. For comparison's sake, it also uploaded a slowed-down video of the Galaxy S8's screen refreshing, which clearly shows a top-to-bottom refresh mechanism. Hence, the Galaxy S8 isn't affected by this jelly scrolling issue.
Mounting The Display Upside Down Is A Design Decision
Why OnePlus and Motorola opted to arrange the screen in such a way remains uncertain, but one of the reasons might be design-related. An upside down screen simply could have lent both companies more leeway in terms of arranging other internal components. It remains similarly uncertain whether OnePlus or Motorola anticipated this kind of effect when designing their phones, but seeing as the effect is extremely noticeable, it's hard to imagine both didn't know from the start.
Should Users Worry?
Some fans have complained about the same issue in previous Motorola phones, although those accounts didn't get much coverage or traction. If you've experienced this in the past using Motorola phones and it didn't really upset you that much, it's likely you won't be annoyed by the Moto Z2 Force.
Motorola hasn't acknowledged the Moto Z2 Force's reported jelly scrolling issue, and it's possible it won't issue a statement unless this whole thing catches significant traction among the Motorola community. It's not clear how Motorola plans to solve this, anyway, since it's a hardware issue.
In the end, your enjoyment of the phone depends on how much the issue irks you, but it's definitely a mildly annoying thing to have to endure, especially for a premium-tier phone.
