Description Germano Massullo 2020-10-27 22:43:05 UTC
Using Plasma *Wayland*, I noticed that Thunderbird-Wayland (is a specific package in Fedora that assures that Thunderbird is using Wayland correctly) and GIMP fonts are a bit blurred,  like when a camera lens is a bit out of focus.

Do you have xdg-desktop-portal-gtk and gnome-settings-daemon installed on your computer?

As far as I know, you need both xdg-desktop-portal-gtk and gnome-settings-daemon to be installed.

Closing this bug report because it's not really a KDE bug.

Why should I need both of them?
