Thank you for the pointer but I think it is another issue.

Thank for the pointer, it seems the same issue. But I am not sure
because I am using the font from Guix.
Well, I have font-dejavu-2.37 and fontconfig-2.13.1 installed in
~/.guix-profile from Guix e98689f.
When I run
guix pull --commit=4bdf4182fe -p /tmp/bad
then
display /tmp/bad/share/info/images/bootstrap-graph.png
there is an issue. Note that 'imagemagick' is installed in
~/.guix-profile using the same commit above.
The commit 4bdf4182fe is the commit of merge. If I pull from the
(left) parent commit, i.e., the commit c81457a588,
guix pull --commit=c81457a588 -p /tmp/left
then
display /tmp/right/share/info/images/bootstrap-graph.png
displays nicely and the font is correct. However, if I pull form the
(right) parent commit, i.e., the commit 23a59b180b,
guix pull --commit=23a59b180b -p /tmp/right
then
display /tmp/right/share/info/images/bootstrap-graph.png
displays wrongly. Well, I have changed nothing, considering the
fonts. And the only difference is commit from "master" vs from
"core-updates". And as I explained [1], it always happens when
core-updates is merged.
BTW, let checkout 4bdf4182fe (git worktree add -b) and run ./bootstrap
&& ./configure --localstatedir=/var/ && make -j4 in "guix environment
--pure guix". Then the image doc/images/bootstrap-graph.png displays
nicely. Idem for the two other commits. It is the same when building
using the -C option.
However, if I pull from this fresh Guix using,
./pre-env-inst guix pull --branch=merge --url=$PWD -p /tmp/merge
then outside the environment, using the very same imagemagick,
display /tmp/merge/share/info/images/bootstrap-graph.png
displays wrongly. Same for the (right) commit 23a59b180b. But it is
not the case for the left commit c81457a588. And as I noted [1] this
happens with all the merges of core-updates.
Something is different between 23a59b180b and c81457a588 in regard to
the font, otherwise the exact same procedure would end to the same
result using the same machine. The question is: does someone
reproduce the same behaviour on Guix System? on other than Debian
foreign distro?
