PDF export subset of pages from desktop app has extra pages with artifacts

[Garmatant]

Tested with desktop app 27.0.9 on Windows 10 64 and Windows 11.

I have a library of diagrams with varying numbers of pages, all where the last page is the background for the others. I want to export all pages except the last to a multi-page PDF. For example, I have a diagram with 4 pages. I want to export pages 1-3 to PDF. Doing so in the desktop app results in good pages 1-3 and a 4th page in the PDF with partial shapes and lines. If I open this diagram on the web version and export it the exact same way, the PDF looks fine. Exporting All pages in the desktop app or web looks fine.

I search through all the discussions here and can't find any similar reports.

Attached are an example Test.xml diagram.

Steps to reproduce:

1. Open Test.xml (from attached Test.zip) in the latest Windows draw.io desktop app.
2. Select File - Export As - PDF with the options Pages 1 to 3, border width of 0 and uncheck Include a copy of my diagram.
3. Click Export.
4. Resulting PDF should only have 3 pages. It has 4 pages and the contents of the 4th page are actual contents of the diagram's page 4 with some pieces of drawings from the other pages.
5. Open Test.xml in the Web version of draw.io and follow steps 2-3 above. The resulting PDF looks perfect.
