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 Touch seeded packages, which is subscribed to ubuntu-themes in Ubuntu. https://bugs.launchpad.net/bugs/1823550 Title: GtkSourceView wrongly has monospaced font in dropdown (context) menu Status in GtkSourceView: Fix Released Status in gtk+3.0 package in Ubuntu: Invalid Status in gtksourceview3 package in Ubuntu: Invalid Status in mate-themes package in Ubuntu: New Status in pluma package in Ubuntu: Invalid Status in ubuntu-themes package in Ubuntu: New Bug description: Steps to reproduce: 1.
