Sencha Touch 2.4 + iOS + Animation started working very fast

Sencha Touch 2.4 + Cordova



I have a code for animateActiveItem - i.e

Code:

---

Ext.Viewport.animateActiveItem(view, {type: 'cover', direction: 'up', duration: 500, easing: 'ease-in-out'});



//also

view.setHideAnimation({type: 'slide', direction: 'down', duration:500, out: true, easing: 'ease-in-out'});

---

In iOS 8 devices, after 5 to 10 minutes the animation is started working very fast.



Any idea why the animation is behaving differently. Please help to resolve this isssue.
