A developer is working on a solution that was recently upgraded to the NEO 3.4 version of the platform.
No code changes were made to reports in the solution.
However, PDF exports of the reports now have horizontal black lines on them. Some lines are black background with white font. Other lines are white background with black font.
The developer is using a class called pd.document.helper.java which appears to be a wrapper of a tool called PDFBox.
Is there something the developer needs to do to not have the black lines in the PDF exports of reports?
