在Chrome浏览器，你会看到一个闪烁的UpdatePanel的，如果你的Ajax响应包含图片网址。我注意到，该闪烁不使用Safari，Firefox或Safari浏览器的移动而不仅仅是Chrome出现，当我删除停止＆LT; IMG SRC =/图像/ photo.png/＆GT; 从Ajax响应的内容。

In Chrome you will see a flicker with the UpdatePanel if your ajax response contains image urls. I noticed that this flicker did not occur with Safari, Firefox or Safari mobile but just Chrome and stopped when I removed <img src="/images/photo.png" /> from ajax response content.
