Strange. Running Debian Unstable (updated). - Cinnamon DE. - Cinnamon desktop theme. - GreenLaguna controls theme. - gnome icon theme. - Bluebird Window borders theme.
Problem: - Gnome programs, such as Gedit or "Disks" (gnome-disk-utility) have one window "theme". - Other programs, such as Nemo, have the Bluebird window theme, as selected in Cinnamon > System Settings > Themes. - Still other programs, such as Chromium, have their own window theme. Is there a way to make at least all main windows of all programs consistently use the same window theme?
