Safari iOS 26 scroll stopping abruptly

[arn]

Affected version

2.3

We just upgraded to Xenforo 2.3. One new behavior is that when scrolling in iOS. If you swipe quickly there is a momentum to the scroll.

With 2.3, we are seeing the scroll stop abruptly. It’s most noticeable for us in a thread view. But also happens in forum view.

I also see it here - only in forum view. I haven’t seen it in thread view but our threads are much longer.

I’ve been trying to debug this on our site but it’s been frustrating.

This seems to be a random issue though. I encounter it more on this forum than I do on mine.

so, I used chat to run through lots of testing. Here's what fixed it. Apologies for pasting ChatGPT logs, but I did isolate the issue.
