Syntaxy is a small and flexible syntax highlighter for the web. It uses one common theme file for all syntax languages to make it easier to customize the appearance to fit your theme. It has no dependencies out of the box, but can be used as a jQuery plugin, if you already have it loaded on your site.
I have noticed on both Chromium and Firefox under Linux and Android that strange clipping occurs to the alternating backgrounds that syntaxy uses. This can be observed simply by resizing the window (reloading). The background does not extend past the initially viewable area of the codebox. I don't see what could be causing this other than that I am unfamiliar with the border-image-* attributes... But this issue is something I have noticed on nearly every site that uses syntaxy-js!
Between Firefox and Chrome I believe this issue could be reproduced on most machines regardless of configuration, since they make up the lions share of the browser market. I will keep poking around and see what I can find.
