Package: libpango-1.0-0
Version: 1.44.7-3
Severity: important
Tags: upstream

Since yesterday's apt full-upgrade of testing, font rendering in Gtk
applications is very bad, kerning is broken, text is wider than necessary,
it's very very unpleasant, I'd even say downright unuable without downgrading.

What I'm seeing is exactly this:
https://gitlab.gnome.org/GNOME/pango/issues/404#note_712911
https://gitlab.gnome.org/GNOME/pango/issues/404#note_676284
https://github.com/harfbuzz/harfbuzz/issues/1892#issuecomment-552877664
so I won't include additional screenshots.

I'm not sure what should Debian do provided upstream seems a bit dead... But
breaking font rendering in Gtk apps across all Debian installations doesn't
seem like a very good outcome either. :-(

Any ideas?

If anyone else is experiencing this, my workaround:

/etc/apt/sources.list:
deb http://snapshot.debian.org/archive/debian/20200401T000000Z/ testing main 
contrib non-free

/etc/apt/preferences:
