Hi,
I tried to make some changes with the patterns (changing from Gnome to KDE etc). When I got to the point where I wasn’t happy with the mess I created, 
, I used snapper to rollback to a previous snapshot. (btw, wow btrfs it’s amazing)
Everything so far is fine, but I got some issue with Adwaita-dark and Nautilus background.
Adwaita-dark is the only theme that doesn’t change nautilus background to dark.
Issue is similar to this fixed bug, but I don’t know how to fix it. I tried to completely remove nautilus and reinstall it, but issue still exists.
Also, I setted ‘gtk-application-prefer-dark-theme = true’ to gtk-3.0/settings.ini but that doesn’t seem to have any affect.
