The boxes drawn in the UI don't render correctly on aerc. Compare to foot.
Any other details? I can't reproduce using aerc v0.14.0 (nor master), calcurse v4.8.0, foot v1.13.1
I still can't get this to replicate, and several on IRC haven't been able to either. Any other info you can give? Do other curses programs show the same issue?
Just calcurse afaict. Don't sweat it if you can't reproduce, I decided against incorporating calcurse into my workflow regardless. Feel free to close or leave open as you see fit.
