I have noticed that after creating pdf forms, during scrolling the form file, sporadic images of the border of the boxes used in the form appear on the top and bottom of the box depending on whether I am scrolling up or down in the file. Although these images are only seen on the monitor and are not printed, they are annoying especially if the form is lengthy. I wonder if anybody has come across this problem and what can be done. In the preamble, I am using:
\usepackage{hyperref}
\hypersetup{ colorlinks=true, pdfstartview=FitH , %
urlcolor=RezumeBlue, linkcolor= black, citecolor=RezumeBlue,
}
