The calculated height when the carousel is initiated is wrong, i get the correct height after the first effect!

I have tried the $(window).load(function() but always the same result, i have tried also setTimeout but in vain!

here is my code :

$(document).ready(function(){
    $(".owl-carousel.style1").owlCarousel({
        autoplay:true,
        items:1,
        loop:true,
        margin: 20,
        smartSpeed:2000,
        autoHeight:true,
        lazyLoad: false
    });
});
