Links are getting rendered with blue background

Hi,

All the links are getting rendered with blue background and with blue text, it looks very bad. All other readers are able to render the same perfectly with white background and blue text.

Please find attached sample pdf, and screenshots of the same. [I am not able to attach the documents in forum, add file doesn't work in chrome and safari].

I request you to please fix the same.

you can try modify:
setAnnotTransparency(0); in Global.default_config().
