Document rendering is different between OSes
This is pretty the same problem as the one described hee: https://ask.libreoffice.org/en/questi..., but this question is closed.
I've a writer document which is rendered differently between Fedora, Windows and macOS. The fonts are the same on the 3 OSes. The exact problem is on Fedora my document is contained on a single page, but on Windows and macOS, it's contained on 2 pages.
This is pretty annoying. Is there a way to fix this?
Just as with the question you refer to, you don't provide a document to test, and specific details on what is different (like a side-by-side screenshot with problematic place marked); nor the specifics on LibreOffice version(s) - and OSes versions as well. And having that former question as a guideline, one could learn on the previous asker's mistakes, and provide all required in advance... sigh.
What specific fonts are used?
Can you see differences in the spacing?
Do the lines wrap at the same place? (character spacing)
Or is there a difference in the line height or line spacing?
Or are the margins just different?
Or do you see a combination of the above?
It would be nice to compare PDFs exported from each OS.
When you say fonts are the same you mean the names that Writer shows or the existing font files in the fonts directory of every machine? Are you sure there is no LO font substitution in any of the machines?
