Physically printing PDF-files with Adobe Reader (2025.001.20474) results in additional lines on the printed page. Can be reproduced when printing with "Microsofot Print to PDF" and saving as PDF. See attached examples: DemoOriginal.pdf is the original file, DemoReexportwithBug.pdf is the result when printing with Microsoft Print to PDF. This is also what it looks like when printed on a physical printer.
