Stuck scroll position

[alexbainbridge]

As per http://forum.ionicframework.com/t/default-scrolling-problem/536

This happens quite a lot and makes the scroll experience jumpy. What happens is that the scroll seems to go "off page" - and then stay there.

Specifically, this seems to happen on scrolling content that has pull to refresh active

I can also verify that this happens on occasion. Difficult to reproduce reliably, but it's definitely something that needs attention as it's such a basic element of the framework.

I see it from time to time too. However, it is not limited to PTR in my experience.

[CoenWarmer]

Agree with calendee, it happens regardless of PTR.

Yep, this needs to be fixed, I keep reproducing it myself. We will get this fixed next week!

I've been able to recreate this reliably on IOS by taking the sample seed app (with the pets) and adding entries. If you one way fast (such that gravity scroll would take you off the end) and then scroll slightly back in opposite direction it freezes. It never freezes if you move within the scroll bounds.

Thanks for the reports and ways to reproduce. It shouldn't get stuck anymore. Read the commit message if you're interested in why it was messing up.

Test it out and let us know how it works!

[CoenWarmer]

Terrific!! Will test now. Thanks guys!!

[alexbainbridge]

Sadly I don't think this is fully fixed

I can still get the content stuck fully off screen (not related to PTR I see, correcting my earlier thought on this)

Hey @alexbainbridge! OK. Can you post the code and device that gives you problems? can you also give a screenshot?

I think it can only bug if you have very specific scroll height combined with a specific acceleration of scroll.

I just got it to happen on this codepen http://codepen.io/anon/pen/aKycF (from issue #425)
Problem is its incredibly difficult to repeat.
Appreciate not being helpful here - apart from pointing out that its not as fixed we think it is!

I'm afraid I agree with @alexbainbridge... Content still occasionally sticks. Due to the difficulty in reproducing I can't tell whether the latest commit had made things better or not. Sorry guys, I think this issue needs to be reopened.
