I just switched from Parabola running GNOME 3.14 to Debian Sid running GNOME 3.14, and the same theme that worked fine on Parabola now isn't applying correctly.The scroll bars among other elements are left unthemed. I got the theme from the Arch package obtainable here.I'm not sure why this particular theme is failing to apply everywhere.This also affects Qt applications such as the Electrum wallet.The top of the window looks correct, but the tabs are unthemed.
Theme not applying correctly
debian;gnome;gtk;theme
Like an idiot, I didn't look at the dependencies for numix-themes on Arch.I didn't think themes needed other packages.To resolve the issue:# apt-get install gtk-engines-murrineand restart the shell (I rebooted).
