The problem is also exists in Gedit, which is by default themed with Ambiance theme from `light-themes` package. Problem confirmed on Ubuntu session (means GNOME) of Ubuntu 18.04.2 LTS and in upcoming 19.04 while running Unity desktop. Here only Adwaita theme looks correct.
So all modern GTK themes should be fixed to correctly show drop-down menu in GtkSourceView. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1823550 Title: GtkSourceView wrongly has monospaced font in dropdown (context) menu To manage notifications about this bug go to: https://bugs.launchpad.net/gtksourceview/+bug/1823550/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
