To find out if your video driver needs upgrading, do this:
In the Control Panel, open the Display folder, select the Settings tab (this screen
has the name of your graphics card), click the Advanced button, select the
Troubleshooting tab. There is an acceleration slide on this page, slide it down a
couple of notches. After you do this, check your Publisher document to see if the
pulsating has stopped.
If your issue is solved go to the manufacturer's web site of your graphics card and
look around for an updated driver.
About the high contrast:
