GVim 7.4 (GTK3) under Kubuntu 16.04 correctly displays the dark solarized theme. However, changing the configuration to
set background=light as detailed in the documentation results in the same dark color scheme after calling
colourscheme solarized again or after restarting Vim with the new configuation. How do I use the light theme in GVim?
PS: I installed G/Vim (GTK3) 8.0 from the git source. It, too, does not display the light theme.
