Random Scroll Jumping?

[JD]

Okay I have been up and down my code on this one and tried removing bits and pieces etc to work out where the issue is coming in but I cannot find it so I'm going to people who are more experienced with diagnosing.... XD

I have a random jump issue in the scrolling of my pages. So, when I scroll down, I'll reach the bottom of my controlled scroll and then it seems to jump a bit further down. When I scroll up, it jumps up when I finish scrolling.

But, what makes it a bigger page is, it doesn't do it all the time! So, I assume I've got a bit of broken code or a code triggering late (it normally happens more often if I'm on a page for longer). But like I said, I can't work out which bit of code is doing it.

This is a good page to test it on: aeipathyrp.com/board/490

And like I said, it doesn't happen on every page load (so you may need to refresh to find it) and, if still no, leave the page open for up to a minute and then it starts to do it.

If anyone can diagnose the problem, I would be muchos grateful!

just to eliminate this as a potential cause -- are y'all ad free? ads can sometimes cause this effect.

Yep, we're actually on forums.net technically - all paid for and ad-free

JD Unfortunately I have been unable to reproduce this issue at all. Is it only on this theme on your forum? Do you have other themes with similar levels of customisation where it does or doesn't have this issue?

The only thing that jumps out at me is that your Recently Updated sidebar coding has a command to parse.icons and the console is throwing an error that it's undefined.

Crap. I was worried this might happen. Like I said, it sometimes happens and then it sometimes doesn't. Which is part of the difficulty in identifying the issue >.<

I don't have any other themes with this level of customisation no >.<

I may simply have to go through the code again, removing different chunks to try and locate the problem. It didn't work last time but if I break it down further perhaps I can at least get in the ballpark of the issue >.<

Edit: If no-one else can produce the issue, I may have to consider the idea that my mouse scroller is somehow broken XD


As for the recently updated sidebar... That's a plugin I have on the forum. How would I go about correcting the error it's throwing? (sorry to be so ignorant >.<)

Many thanks again for your continuing, awesome help Kami! <3

TBH the recently updated sidebar error is probably just a red herring — I can't see why that would cause any page "jumping", but it's the only anomaly I could find on the forum, since the issue never occurred for me. I would reach out to the plugin creator in their support thread (I believe the author is Todge) for them to troubleshoot.

If this level of customisation is only present on this theme, and it doesn't occur anywhere else on the internet or with any other theme on your forum, then it does point to a theme issue... I just can't repro it, which means I can't diagnose.

When did it start occurring? Do you remember the last change you made before you noticed the issue?

Honestly, I can't remember what I was doing when I first noticed it and I'm not the only staffer working on the code of the site so I wouldn't necessarily be able to pinpoint the cause if I did. That's part of the frustration. I will definitely post in the plugin support thread just to be sure, or at least to get that error cleared away. As for the original issue of the thread... I actually cannot reproduce the error now either. So, either something I removed during my testing has worked, or I had a crumb on my mouse scroll wheel XD - for now, I think this thread can be marked as resolved and if the issue returns I'll repost.

Apologies for the hassle and thank you for looking over the errors for me Kami <3

Look at this point in my career if something broken starts working for Unknown Reasons I just roll with it and thank the Tech Gods for their generosity :P

Yeah it's worth posting in the plugin thread regardless of whether not it was the cause; if it's having an error now, there's no real telling what sort of cascading affect it could potentially have in the future, so erring on the side of caution is wise (and the error could in of itself be a false flag).

Best of luck, you know where to find us if you need more help :)
