Ghostscript is also using fontconfig to search for font files
For more information, see /usr/share/doc/ghostscript/Use.htm.
On debian system you may need to install ghostscript-doc package.
Please report bugs to bugs.ghostscript.com.


i had no  ghostscript-doc package installed. I installed it.

In your screen capture, 'Arguments' is '-dFIXEDMEDIA-dFIXEDMEDIA-dFIXEDMEDIA-dFIXEDMEDIA'. It should be just a single '-dFIXEDMEDIA'. It is not necessary to repeat it four times, and repeating it with no space might set a variable with the name 'FIXEDMEDIA-dFIXEDMEDIA-dFIXEDMEDIA-dFIXEDMEDIA' instead of setting 'FIXEDMEDIA'.

If gs took 0m53.922s (nearly a minute), the problem is gs, not gv.

> I think the problem is about font paths.


I agree. The file displays instantly for me with several versions of gs.

Try running `gs -h` and looking at the `Search path:` list near the end.
Also try running `printenv | grep GS_` to see if you have set GS_OPTIONS, GS_FONTPATH, or GS_LIB

The search path might have a directory with a huge number of files or a directory that is a slow network mount.

If you want to see everything that gs is trying to open, you can use `strace`, for example, `strace -e openat gs sample@file.pdf`

> Yes it is ok to share it.


Thanks. I think that it shows an issue with gs 10.

Yes it is ok to share it.
Yes gv is build from source, but i didnt changed something, if i remember correctly.

If i must have the last edition, then i must build from source most.

I attached screenshot of the gs options.

Yes, i had no specific problem with other multi-page pdfs.

I think the problem is about font paths.

Time:
real 0m53.922s
user 0m1.077s
sys 0m0.366s

I meant to show how many seconds the `time` command returned.

Your gs installation has a strange search path with items like `/usr/share/ghostscript/9.53.3/Resource/Font//usr/share/ghostsc.` Check if you set any environment variables with `set | grep GS_` or if you built gs from source, check if you customized the build.

I think that the errors that I had were from gs 10, and your file might be ok. Is it OK if I pass that file to the gs developers in a bug report?

gv works from postscript. When it gets a pdf, it runs the pdf through pdf2dsc to find the list of pages and pdf2ps to convert it to postscript. You can see the commands if you start gv and then on the menu bar at the top, click on `State -> Ghostscript Options...` If your gs search path is an indication of a messed up gs installation, maybe some of the gs parts that gv uses aren't installed correctly.

Do other multi-page pdf files work in gv for you?

It works quickly for me on Fedora 36 with gv 3.7.4 from my git clone and gs 10.00.0.

Try running
  time gs -dNOPAUSE -sDEVICE=x11 -email is unavailable- -c quit

On my laptop, it shows the pages and exits in 0.2 seconds.
If it takes much longer for you, the problem is gs (ghostscript) not gv.

When I run the gs command above, I get the errors below. gv and gs are unpredictable on corrupt files. See if you can make a PDF with no errors that takes much longer in gv than gs.

The following errors were encountered at least once while processing this file:
        error executing PDF token

   ** This file had errors that were repaired or ignored.
