I removed

background: url(none);

in my stylesheet because of load performance http://stackoverflow.com/questions/2577422/why-firebug-pretends-that-my-stylesheet-is-calling-my-xmlrpc

The problem is that it now causes some glitch on css list.

Any idea how to fix this ?

Thanks.

Update: picture below

Tried to put background: none as suggested but didn't solve the problem/

ul.sidebar_list li ul li ul {
    margin: 0px;
    padding: 0px!important;
    float: left;
    width: 100%;
    list-style-type: none;
    background: none;
}
