I noticed a difference since the december 2021 update when printing pdf's from PBi Desktop. There is significatly more space in between the border of the pdf file and the border in PBi Desktop. This was not the case in previous versions.
Border PBi Desktop
PDF Printout. The rectabular border reflects the border of the page in PBi Desktop.
What I also noticed in previous PBi Desktop versions is that the pdf printout is affected by the Filter- Visularizations- or Fields pane beeing collapsed or not. When a pane is expanded, objects in the report of the pdf file are slightly moved from one printout to the other. It is a very slight movement, but still visible when the same report page printout is repeated several times and attached in one pdf file. When moving from one page to another, objects are slightly moving. This is not happening when exporting to pdf only when any pane is collapsed.
