Users of the Motorola Moto Z2 Force are reporting a "jelly" effect that results in screen distortion in certain cases. Yes, you are right, the problem is similar to what OnePlus 5 users reported back in June.
An user on XDA (Daniel Marchena), who faced the issue, recorded a video of their unit, clearly showing the problem:
In the user's own words, the issue is "especially noticeable if you look at the word 'Display' while it is scrolling." He further added, "If you look closely you can see that the panel on the Moto Z2 Force actually refreshes in the opposite direction than the Galaxy S8+, an indication that the display is mounted in an inverted orientation."
The following video shows display panel refresh on the user's Galaxy S8 unit:
Interestingly, if you recall, the jelly effect on the OnePlus 5 was also tracked down to screen being mounted upside down.
Marchena also noted that several Motorola phones in the past have had the same issue, just that it received widespread press coverage when the problem was spotted on the OnePlus 5.

This cannot be fixed via a software update.
