JQuery UI可拖动元素在Chrome中留下了奇怪的痕迹

I'm trying to make my first chrome extension here.It's a sticky note board. But when I try to drag the first element on my board using JQueryUI it leaves horizontal lines as traces in chrome.

我正试图在这里制作我的第一个镀铬扩展。这是一个粘滞便笺板。但是当我尝试使用JQueryUI拖动我的主板上的第一个元素时，它会将水平线留在chrome中作为跟踪。

Here's a screenshot.

  </ul>

and the javascript

和JavaScript

$(document).ready(function() {
    $(function() {
        $(".dragable").draggable().bind('click', function(){
          $(this).focus();
        });
    });

    $('.dragable').bind('click', function() {
        $(this).attr('contenteditable', 'true');
    }).blur(
        function() {
            $(this).attr('contenteditable', 'false');
        });
})

Note: After some experimentation I found that the problem is with -webkit-transform If I comment them out, the problem doesn't show up.

注意：经过一些实验，我发现问题出在-webkit-transform上如果我将它们注释掉，问题就不会出现了。

Finally I have a working workaround .

最后，我有一个工作的解决方法。

Just using outline: 1px solid transparent; on the div fixes the problem :)

只需使用轮廓：1px实心透明;在div修复问题:)

It's an anti-aliasing issue.

这是一个消除锯齿的问题。
