Avizo had some issues that ultimately made me return to the old and
reliable dunst. For example, the home-manager service would fail to
restart after the computer was idle for a set amount of time.
The way avizo manages its window also resulted in compositors like
Hyprland and picom showing a blur artifact when avizo tried to fade
itself. Ultimately using dunst simplifies things and avoids having
to look in two different places for notifications.
