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? [1] http://issues.guix.gnu.org/issue/41282 All the best, simon
