I know the topic is old ... but I had this here and I wanted to share.
In case anyone wants responsive on this issue, it is a little sloppy, but it will.
Copy the following code at the end of style.css file of your theme and ready:
Code:
.widget_recent_entries ul li{height:25px;overflow:hidden}
@media (max-width: 1253px){
body{background-image:none}
