The previous MenuAfter.jpg shows the "normal" behaviour, even after the "--reinstall".
This MenuBefore.jpg shows how it looks like when I did my correction: "1. Opened /usr/share/themes/Ambiance/gtk-2.0/gtkrc with sudo nano 2. Searched for line containing: style "menu" 3. This line looked like this: style "menu" = "dark" { 4. Now changed it to: 5. style "menu" = "white" { 5. Saved the changes and rebooted " ** Attachment added: "MenuBefore.jpg" https://bugs.launchpad.net/ubuntu/+source/ubuntu-themes/+bug/1743710/+attachment/5041543/+files/MenuBefore.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1743710 Title: Ubuntu 16.04: since 2018 all dropdown menus black and unreadable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-themes/+bug/1743710/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
