Bounce back has strange behavior on chrome 45

[bertyhell]

When doing a strang flicker movement with my mouse on chrome desktop, the bounce does a weird jump and then does the bounce animation.

I can also get this behavior in the demo:
http://lab.cubiq.org/iscroll5/demos/simple/

It's like it does the bounce animation from the wrong direction.

Video of this behavior:

My code:

        scroller = new IScroll(element[0], {
          mouseWheel:            mouseWheel,
          scrollbars:            needsScrollbar ? 'custom' : false,
          scrollX:               horizontal,
          scrollY:               !horizontal,
          shrinkScrollbars:      'clip',
          interactiveScrollbars: true,
          eventPassthrough:      true,
          bounceEasing:          'back'
        });

The video would be more understandable if there were different images

But I get what you mean, with the pace of iScroll development, your best bet is probably to manually modify/improve the bounce routine

Is this on a low performance device by the way? (+ which OS?) - generally, low performance causes issues like these, where slowing due to low performance sometimes reflect as anomalies / speed bursts etc.

It's a high powered device:
Desktop windows 10, i7 CPU.

I'll see if I can redo the video with higher framerate and different images

I experience the issue on http://lab.cubiq.org/iscroll5/demos/simple/ too - using OSX/Latest Chrome, there is a weird pause and then a bounce

I wonder if this: #973 could fix the issue

Here is a script with the above fix and more applied, so that you can use for testing: https://www.geobird.com/js/iscroll/iscroll-5.1.3.c18.js?v=5

Yes that fixed it.
Hopefully that pull-request will make it in soon :D

Interesting to know, thanks for the info

Don't hold your breath for the PR, manually apply your fixes to iScroll :)

(iScroll seems to have major releases, so I'm guessing the PR wouldn't apply to the next release anyway)

I tried the pull request but I get the same behavior ..

I think iScroll is not supporting since last year (latest commit)
