There is a very rare issue of compatibility between java and certain graphics cards on Windows XP.

When this happens, the PDF will display scrambledweirdly with some part that may repeat. 

We found a few forums that reported similar problems.

Read this posting on Microsoft’s website.

Here are a few things to try:

  1. Your best bet is to update the driver for your graphics / video card.

  2. Another thing to try is to disable hardware acceleration for graphics. To do this, right click on the desktop and choose Properties. In the dialog that shows up, go to the Settings tab and then press Advanced. The Advance dialog should / might have a tab called “Troubleshoot” where there should be a setting to disable hardware acceleration.
  3. Try to change the settings on the graphics card to see if this will resolve the scrambled display.
  4. Try to change the resolution of the monitor and see if this has any effect. Changing the resolution to a lower setting has worked for some users.
