Document Builder Generates Blurry Data - Doubling Effect

When generating a document and sending as an attachment in an update notification request, recipient complains the text field data has a doubling effect. This makes the text too blurry to read. I've tested the auto generation by sending the update request notification with the attachment to myself. When I do that, it generates as expected with no blurring. When I open the document directly in the sheet, it is not blurred. I do not understand what is happening or how to fix it.
