Top bar menu is badly rendered
I switched to Fedora 30 and saw this when clicked on the menu on topbar
After some time it fixed itself but remained unresponsive and doesn't reflect actual state (on the image bellow you can see, that icon above the menu shows that the sound is unmuted, but in the menu it's muted)
