Hi, I've noticed that the recent Lyx versions (2.3.x) generate a PDF that is of "US Letter" size, even though I've explicitly set up A4 in the document settings (Page Layout -> Format). This happens once I enable Hyperref support in the document settings.
As suggested in https://tex.stackexchange.com/questions/356545/why-does-the-hyperref-package-change-the-paper-size it seems that adding "a4paper" as custom option to the documentclass seems to work. This is extreme expert knowledge that you should not expect your users to have. When a normal/novice user sets up A4, then the generated PDF should be A4 (and the same goes for any other page format). Is this something that you could fix? Best regards! Marius
