Budgie Raven is huge when over 100% volume bar requested
Created by: fossfreedom
Using Ubuntu Budgie 18.10/19.04 but would equally apply with an up-to-date Manjaro Budgie or Solus Budgie (does not apply to Ubuntu Budgie 18.04 unless you are running with the UB backports PPA)
If you remove the calendar widget from raven and tick the over 100% volume setting in budgie-desktop-settings - Raven ... then logout and login, raven is shown as above.
Upstream budgie desktop keep closing bug reports such as this via a "use a recognised compatible theme such as Plata"
Plata styles this slider bar that has a tick mark using https://gitlab.com/tista500/plata-theme/blob/master/src/gtk/sass/common/_3rd-party.scss#L868
