Not really
The only thing that occurs to me is that bxslider has a callback which fires when the slider is loaded (onSliderLoad), so you could use that:
$('.bxslider').bxSlider({
minSlides: 3,
maxSlides: 6,
slideWidth: 170,
slideMargin: 10,
onSliderLoad: function(){
$(".bxparent").hide();
}
});
You would of course have to ensure that the bxparent is visible on page load.
Other than that, you can get around the problem by using visibility:hidden
and visibility:visible
instead of display:block
and display:none
