Did some more tests with the failing screenshots in my project, installing the package
fonts-dejavu-corein the 1.17 container before running the tests solves the problem (no other modifications), the snapshot tests succeeded without errors again.When comparing packages installed in the containers, the difference seems to be due to the removal of the
fluxboxpackage, which was installed in 1.16.3 but isn’t anymore in 1.17.0. Dependencies of fluxbox (> libfontconfig1 > fontconfig-config > fonts-dejavu-core) then triggered automatic installation of the font, which apparently is selected when available by Firefox.Maybe consider installing at least the specific font package in the official Dockerfile again to restore the old behavior?
Hi👋, I have the same issue between Docker v1.12.3-focal and github action ubuntu-20.04
When I added this code, the problem was solved.
Font-family and compatibility between Linux, Windows, MacOS X
The problem seems to be that Docker v1.12.3-focal only have Liberation Font
These are github ubuntu font lists:
