Good day, I was testing Plasma Wayland 5.20.1 from zawertun/kde Copr repository, when I noticed Thunderbird fonts being blurred like when you use a photocamera with a lens that is a bit out of focus. I opened this KWin bugreport https://bugs.kde.org/show_bug.cgi?id=428367 but I have been told [1] that I need both xdg-desktop-portal-gtk and gnome-settings-daemon to be installed, I don't know why What can be the correlation between blurred fonts and these packages?
