Over scroll when scrolling inside sections with scrollOverflow:true using trackpad

[janzaba]

Hello!
I found an issue. You can see it on this demo page:
http://alvarotrigo.com/fullPage/examples/scrolling.html#firstPage
Bug appears if you scroll page too fast. When you scroll first section too fast, secound section shows scrolled down.

This bug appears on Firefox (mainly on mac), when i'm using touchpad. Didn't see this when i used mouse. Safari and Chrome are clean.

Btw. Great plugin :)

. When you scroll first section too fast, secound section shows scrolled down.

You mean, it scrolls down two sections when you just want to scroll one?

It looks like you are scrolling too hard and the kinetic scrolling inertia is firing the second scroll.

Possibly a duplicate of #310

It would be greate if you can provide a video where I can see the screen and your trackpad.

#310 is not exactly what i mean. My point is an inside scroll.. Here is my video:

I'm using only short swipes and sometimes it scrolls properly, sometimes not. The difference is almost imperceptible.
I understand that there is a limit, and when scrolling is longer, the inside scroll starts. But i noticed, that inside scroll starts before scrolling animation ends. I think plugin should prevent inside scrolling until animation ends.

So it should be like this:
i scroll -> section reaches end -> changing sections -> section change animation ends -> if i still scrolling inside scroll starts.

I hope I explained well..

I found an idea. I've looked into your code and noticed that slimscroll is activating at the page load event, am i right? Maybe better idea is to activate slimscroll on active slide, after scrolling animation? What do you think?

[alvarotrigo]

It doesn't seem to be Firefox specific but more about kinetic scrolling.

slimScroll uses wheelStep : 20, by default. Fullpage.js doesn't provide a way to change the options, but you can take at this pull request and apply a similar change to achieve your result.

Fixed in 2.8.0.

Using 2.8.0. Just like to report I am seeing this problem when a anchor is clicked 2nd times (first time is ok).

[alvarotrigo]

Using 2.8.0

Only the latest version is supported. Which at the moment is 2.8.6.

This was solved in fullPage.js v4 🥳
