Perhaps I missed it, but what is the Linux «based on Debian 11» you
use?  Is it one of the ubuntu family, like Xubuntu?  Is it Linux Mint'
/Mint/, or the LDME 4 closer to Debian than Mint's Mint?  Perhaps
something specific to your distribution contributes to the problems
you report which might be beyond reach of Gnuplot.

Curiosity aside, I just fetched Gnuplot (Version 5.4 patchlevel 3,
last modified 2021-12-24) from sourceforge, decompressed the tar.gz
(4.5 Mo).  The INSTALL file (no file extension) describes well what
has to be done to perform the installation, which starts by entering
the decompressed archive from the terminal.  Then run from the
terminal `./configure`, followed by `make`, and `make check`.  For
the then following installation /per se/, you possibly need elevated
administrator privileges, i.e., `sudo make install`.  True, you have
to request `synaptic` once to get GNU Make (e.g., GNU Make 4.3 by
2020) to run the make command.  In my case, it overwrites synaptic's
earlier installation of Gnuplot 5.4 patchlevel 2 from Debian's
repositories.

Caveat: The installation based on the sourceforge archive does not
offer you access to wxterm, pngcairo, epscairo, or pdfcairo terminal.
Yet have the postscript terminal instead to generate a .eps with the
two-line plot title with escaped ampersand and both lines in serif
fonts greater than usually seen (by appearance /likely/ a different
serif font than the by Bistream Vera).
