It looks like the problem was introduced in df45af90413906b18710d8c51c44afd5b92d6db6 when upower was updated to version 99.11. I also expect it is related to gnome-tweaks, which is out of date. I'm going to see if updating gnome-tweaks fixes it. If so, I'll send an update patch. If not, we can determine if it's worth reverting upower.
