Hi Luigi, ps.map (or g.gui.psmap/File > Cartographic Composer) is certainly an option. You can also have a look at m.printws in addons (mentioned in the ticket you linked), but it suffers from the same issues as the normal display since it is using d-commands.
https://grass.osgeo.org/grass78/manuals/addons/m.printws.html I have tried to put individual layers rendered as SVGs together manually. That was too difficult to match, but perhaps if you clip vectors to a computational region you can match those. Just to be clear, are you saying the ps driver (with GRASS_RENDER_PS_TRAILER etc) didn't work for you?
