Geoserver ExternalGraphic draw icon incorrect

I run into a problem with Geoserver.

I'm drawing multiple icons which each represent a place all over my map using ExternalGraphic. But geoserver didn't draw them correctly as they are. I attach an image as the result of geoserver drawing:

Image example of error

As you can see, the 2 car icon, both got cut off around 1 pixel comapre to its original size (1 got cut off from top down while another from bottom up). It make same icon look differentfrom place to place. And i think because of this cutting, after lose some pixel, they resize the image back to its original size, which make the $ on top left look blurry compare to the one next to it.

Also as in External graphic document mention, i didn't use any Size attribute so they won't get resize or anything. So i'm not sure why the image got cut off like that.

Any1 can help me about this case ? Thank you in advance.

Solution

I suggest you open a report at http://jira.codehaus.org/browse/GEOS attaching one of the images and your style document.
