Bug#1107962: libwebkit2gtk-4.1-0: After upgrade, breaks evolution display of messages, liferea previews

Wed Jun 18 04:52:59 BST 2025

Package: libwebkit2gtk-4.1-0
Version: 2.48.3-1
Severity: important
Tags: a11y

Dear Maintainer,

After an apt upgrade over the weekend (and system reboot), evolution
emails are displayed with a white background, even with dark mode/theme
enabled. That's an accessibility-related issue for me.

I tried a custom css (the same gtk.css is both in ~/.config/gtk-3.0 and
~/.config/gtk-4.0). I also tried disabling the webkit sandboxing. In
both cases, the issue remained.

I initially reported the issue to upstream evolution (as suggested by
the reportbug utility)
at https://gitlab.gnome.org/GNOME/evolution/-/issues/3078.

But then i noticed liferea's previews were not displayed as well.

The evolution guy specifically asked for a webkit version, and in the
upgrade that package is common to both evolution and liferea.

When launching liferea from the terminal, the output is

$ liferea
