last slide scroll glitch

Hi there,

I’m facing an issue when reaching the last slide on slick slider and trying to scroll back to the previous slide. Below I am sharing a video depicting the issue.

As you will see below the last slider I am trying to make the footer show, which is not a part of the slider. But when scrolling back from the last slide, the transition is not smooth and I don’t know how to fix it.

Also, I am using the below script for the slider:

// debounce from underscore.js
function debounce(func, wait, immediate) {
var timeout;
return function() {
var context = this, args = arguments;
var later = function() {
timeout = null;
if (!immediate) func.apply(context, args);
};
var callNow = immediate && !timeout;
clearTimeout(timeout);
timeout = setTimeout(later, wait);
if (callNow) func.apply(context, args);
};
};

// use x and y mousewheel event data to navigate flickity
function slick_handle_wheel_event(e, slick_instance, slick_is_animating) {
// do not trigger a slide change if another is being animated
if (!slick_is_animating) {
// pick the larger of the two delta magnitudes (x or y) to determine nav direction
var direction =
Math.abs(e.deltaX) > Math.abs(e.deltaY) ? e.deltaX : e.deltaY;

//console.log("wheel scroll ", e.deltaX, e.deltaY, direction);

if (direction > 0) {
  // next slide
  slick_instance.slick("slickNext");
} else {
  // prev slide
  slick_instance.slick("slickPrev");
}

}
}

// debounce the wheel event handling since trackpads can have a lot of inertia
var slick_handle_wheel_event_debounced = debounce(
slick_handle_wheel_event
, 100, true
);

// init slider
const slick_2 = $(“.elementor-139”);
slick_2.slick({
dots: true,
vertical: true,
// verticalSwiping: true,
speed: 1000,
initialSlide: 1,
easing: ‘linear’,
adaptiveHeight: true,
arrows: false,
draggable: false,
swipeToSlide: false,
waitForAnimate: false,
infinite: false
});
var slick_2_is_animating = false;

slick_2.on(“afterChange”, function(index) {
//console.log(“Slide after change ” + index);
slick_2_is_animating = false;
});

slick_2.on(“beforeChange”, function(index) {
//console.log(“Slide before change ” + index);
slick_2_is_animating = true;
});

slick_2.on(“wheel”, function(e) {
slick_handle_wheel_event_debounced(e.originalEvent, slick_2, slick_2_is_animating);
});

$(document).ready(function(){

 $('.elementor-139').on('afterChange', function(event, slick, currentSlide){
  // Hide all content elements
  //$('#main-footer').hide();
     $("#main-footer").css({"visibility": "hidden","display": "none"});

  // Show content only for the last slide
  if (currentSlide === slick.slideCount - 1) {
    //$('#main-footer').show();
      $("#main-footer").css({"visibility": "visible","display": "flex"});
      //$('.elementor-139').slick('unslick');
  }
});

});

Thank you in advance
