这是一个在Internet Explorer中固定背景图片的已知错误。我们最近做了一些工作来改进这种行为，并将更新发送到Windows 10上的Internet Explorer预览版本。您可以在 http://remote.modern.ie 。

This is a known bug with fixed background images in Internet Explorer. We recently did some work to improve this behavior and have shipped updates to our preview build of Internet Explorer on Windows 10. You can test the changes today from Mac OS X or Windows on http://remote.modern.ie.

下面是前后的IE 11和IE Remote预习。请注意，使用鼠标滚轮的滚动不会像在Internet Explorer 11中那样导致固定的背景图片跳跃（或抖动）。

Below is the before and after, IE 11 and IE Remote Preview. Notice how scrolling with the mouse-wheel no longer causes the fixed background image to jump (or jitter) as it did in Internet Explorer 11.
