A version of Emacs compiled from git (27.0.50), using GTK 3.22.21
(openSUSE Tumbleweed) do not show the selection text.

There is a text error in *Message* buffer:

Unable to load color "gtk_selection_bg_color"


Does reverting commit f6818e761eaafe095e07249180dc8f9a329f1473 help?
(For context, in newer versions of GTK+ the concept of a background color is deprecated because backgrounds can be arbitrary pictures.)
