Hello, thanks for opening an issue with us! Sorry, but i'm not understanding the issue fully. Would you mind creating a repo that i can use to test this issue? Thanks for using Ionic!

I have set {initialSlide: 1}.The initial index of second pages, but in version beta. 11 can see first display the first page, and then automatically jump to page second.In version beta.10,show second pages at once.

I have that same issue with the { initialSlide = ...} option. After the page with the slides has loaded, you can see (for a short time) the first of all slides and then the desired 'initialSlide'.

I tried to work around that issue and implemented a slider.slideTo(initialSlide, 0, false) statement within the various page cycle events (ionViewLoaded, ionViewWillEnter, ionViewDidEnter). Only within the ionViewDidEnterevent the slideTo-statement works as expected and jumps to the 'initialSlide', but with the same tiny lag after showing the first of all slides. So no real workaround.

still flashes first slide in rc0, before showing initialSlide: x

There are few bugs with initialSlide option:

1. Flickering of the view
2. After init with initialSlide option, you can't call getActiveIndex(), error: ORIGINAL EXCEPTION: Cannot read property 'activeIndex' of undefined.

I believe this is caused because the slide is changing to another one and ionDidChange is called

    this.horizontalSliderOptions = {
      loop: false,
      pager: false,
      direction: "horizontal",
      initialSlide: 1
    }

  (ionDidChange)="onSlideChanged()"

  onSlideChanged(e) {
    let activeHorizontal = this.horizontalSlider.getActiveIndex()
 }

This bug is still present in Ionic 2 RC2. Maybe you can change the title of the issue?

And also in RC3 :-/
