Matcha GTK theme stable version 20200403-1 produces following warnings to terminal after start of GTK application (for example Firefox):
Gtk-WARNING **: ... : Theme parsing error: gtk.css:6536:26: 'dakren' is not a valid color name Gtk-WARNING **: ... : Theme parsing error: gtk.css:6539:22: 'dakren' is not a valid color name
Problem is probably resolved in today's update of upstream (https://github.com/vinceliuice/Matcha-gtk-theme/issues/109)
Thanks for solving.
Under the line:
I noticed that on Manjaro GitLab is still version 20200329 ... even if in all branches is 20200403.
