This bug boggles my mind. Looking at the human-theme Launchpad code page https://code.launchpad.net/~ubuntu-art-pkg/human-theme/ubuntu it looks like the code for the Human theme packages hasn’t been updated since 2011. Why would it stop working now?! Maybe a bug needs to be filed with GTK?
(I’m also using Ubuntu MATE 18.04 LTS. This problem began for me when I upgraded from 16.04 LTS.) I’d like to see this fixed, the Human theme was the last vestige of the 2000s-era Ubuntu I loved :( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1721955 Title: Human and Human-Clearlooks themes have incorrect gray window title color To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1721955/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
