Some components of cinnamon were updated to version 3.4 in my last world update. These components included gnome-extra/cinnamon, gnome-extra/cjs, gnome-extra/nemo, gnome-extra/cinnamon-desktop, gnome-extra/cinnamon-menus and x11-wm/muffin. However, I've noticed several new bugs when running cinnamon 3.4 including a that DPI scaling is no longer functional, icon and window themes do not function and that color management no longer detects my monitor. I noticed that the upstream Gentoo tree has more cinnamon components upgraded, including gnome-extra/cinnamon-settings-daemon which remains at 3.2.0 in Funtoo. I am unable to rollback cinnamon to a working state in 3.2, ostensibly due to the removal of cjs 3.2 from the tree (trying to compile gnome-extra/cinnamon-3.2.7 fails looking for a cjs component).

Installing gnome-extra/cinnamon-settings-daemon-3.4.0 fixes these issues.
