Hi,
I've reported an issue that seems to be a bug with negative -fx-backgound-position values in CSS : the background image is painted out of bound of the target node.
Here is the CSS code:
/* useradd icon style: with negative offset */
.icon-useradd {
-fx-background-position: -90px 0px;
}
I've created a new JIRA issue with attached screenshot :
