Source: gtk4 Version: 4.15.5+ds-2 Severity: important Forwarded: https://gitlab.gnome.org/GNOME/gtk/-/issues/6907
A new test added in gtk4 4.15.* is failing on multiple architectures. I skipped the test on Debian and reported the issue upstream. Perhaps it's a rounding or precision issue. It was unclear to me whether the test assumptions are broken or whether the css parsing code needs to be adjusted. Thank you, Jeremy Bícha
