JavaScript "while-loop" doesn't work on Safari

Hi guys, i hope you could help me with a JavaScript problem. I just wrote a little javascript code for a parallax effect on my header image and title. It all works well in Chrome, Firefox and Opera but on Apples Safari the browser crashes instantly. Its like a endless "while-loop" but i think there isn't any endless loop. So i hope you could help me. Oh and on CodePen it also does't work:

 $(document).ready(function() {
    var win = $(window),
        title = $('.title'),
        header = $('.header'),
        header_height = header.height(),
        header_img = $('.header_img'),
        img_height = header_img.height(),
        img_diff = img_height-header_height,
        i = 1,
        x = header_height/i;

    win.scroll(function(){
        var winPos = win.scrollTop();
        // Doesn't work on Safari:
        if (header_img.length != 0) {
            while(x > img_diff){
                i = i + 0.1;
                x = header_height/i;
            }
        }
        if(winPos >= 0 && winPos <= header_height){
            title.css({
                top: -50 + winPos/3 + "%",
                opacity: 1 - winPos/150
            });
            header_img.css({
                top: -winPos/i
            });
        }
    });
});

Thanks (:
