That definitely is not happening on this end.
It is probably something in your custom CSS. If you turn it off I think this issue will go away.
However, you can add this to the bottom of your CSS to override whatever you have that is causing this issue:
#content,
#open-or-check,
#check-ticket,
#complianceouter,
#compliance,
#more-options,
#information,
#footer {
background-image: none !important;
}
Let me know if this helps so I can mark this as resolved.
