Hi,
When I am exporting PDFs of pages in my personal space on Confluence cloud, there is always a small gradient at the bottom of every page except for the title page:

I've deleted all styles for the PDF export for debugging purposes so the gradient cannot be coming from any CSS.
I've also tried exporting pages in my space as HTML but the gradient is missing there. It must be connected to the PDF export.
Does anybody have an idea where the gradient could be coming from and how to remove it?
Thank you,
Anne
