White background with ie8

I just found a miscellaneous error: everything is working fine in firefox but ie8 has a big white background of the li.views-showcase-pager-item.

I could not found the css rules for this but ie8 debugger (haha) says: this element has an inline style like "background:#ffffff;".

I just found it in the jquery.cycle.min.js:
if(v&&v!="transparent"){return v;}}return"#ffffff";}

I changed it like this:
if(v&&v!="transparent"){return v;}}return"transparent";}

Then the bug disappeared.

I am using trasparent background pngs for my showcase this white background was very frustrating.

Are there any reason for this inline white background? How can I remove it with simple css rule?

THX!
