Hi!
I have a fresh install of ubuntu Budgie, and i have a issue of size with the Raven panel. He is to small and the text of my notification or input/output audio is crutch.
Have you got a picture to share?
What theme are you using?
What is your screen resolution?
What’s the resolution you are using on your machine? Is the panel maybe stretched ?
It may be the size of the interface fonts in the budgie desktop preferences that is set too small.
