Inkscape list several issues for snap version Inkscape 1.2
The one that affects me is an issue of exporting files. Inkscape website states this is a vendor problem:
If you try to save as PDF or any other non-SVG file format and Inkscape creates an SVG file instead that only has a different file extension and does not open correctly in the program it should be opened with, this is usually the result of outdated xdg-portals. Please talk to your desktop vendor about updating them.
The application is saving to a directory /run/user/1000/doc/ <8 character hexidecimal>
and creating a file in the target directory that looks like .xdp_<file name>.ZDP701.
Have the outdated xdg-portals mentioned been fixed?
