为什么我的转换：chromeY在Chrome中闪烁？

Question

我有一个简单的多列布局;我尝试使用:hover在translateY上解除元素。

它会导致闪烁（在Chrome 57上测试）。我该如何解决这个问题？

"use strict";

$(function () {
  var $target = $('.wall');

  function getImageUrl(id) {
    var width = 500;
    var height = 250 + Math.floor(Math.random() * 150);
    return "https://unsplash.it/" + width + "/" + height + "?image=" + id;
  }

  function addElement(element) {
    var $template = $target.find('.template').clone().appendTo($target).removeClass("template");

    $template.find("a").attr("href", element.post_url);

    $template.find("img").attr("src", getImageUrl(element.id));

    $template.find("figcaption").text(element.author);

    $template.removeClass("hide");
  }

  $.getJSON("https://unsplash.it/list", function (data) {
    var images = 12;
    var elements = [];

    function getRandomImage() {
      var id = Math.floor(Math.random() * data.length);
      return data.splice(id, 1)[0];
    }

    while (images > elements.length) {if (window.CP.shouldStopExecution(1)){break;}
      elements.push(getRandomImage());
    }
window.CP.exitedLoop(1);


    elements.forEach(function (element) {
      addElement(element);
    });
  });
});
