Ionic2 Nav Push - previous page not sliding out

Hello everyone,

I’m driving nuts, our app stopped working all of sudden. The navigation stack is not working as before

We have to pages and to navigate between them we use:

nav.push(OurComponent, { param: ourParam });

The next page is overlaping the new one which is not sliding out as before. Is this a browser issue or what?

I found out the issue. That is really weird, bnut I can understand. The problem of using push, ist that the page is always in the DOM and this particular page had no background color and then this behavior of overlaping. I think my problem is to understand when using push and when using setRoot.
