Pushed to unstable as of budgie-desktop rel 218 with respective commit in budgie-desktop here.
Edit: Subsequent commit of rel 219.
There's some other bits in unstable at the moment that are needing testing (like kernels with BleedingTooth bluetooth security patches), but once more of that has been validated I'll do the sync.
In the meantime, if you want to run the following command, it should install the latest budgie-desktop from unstable (identical to what you'd get in stable) if you want to validate the fix 🙂
sudo eopkg install https://mirrors.rit.edu/solus/packages/unstable/b/budgie-desktop/budgie-desktop-10.5.1-219-1-x86_64.eopkg
Make sure to do
budgie-panel --replace &! in a Terminal after installation, then press
Ctrl+D to detach from the running process (which will close the Terminal unless you're using something like tmux, in which case it'll close the tmux pane or window instead).
Edit: updated from 218 to 219 rel.
