I am a new user of Manjaro KDE plasma.I updated the system and the then installed apps.Then I changed my theme colors to dark but some apps like firefox , pamac , evolution,etc. did not sync up with the theme . I googled about it and I came to know that plasma 5.20 dropped support for changing themes.
Plasma doesnt touch the ~/.gtkrc-2.0 file anymore.
I will leave here mine so you can use it to create or edit your own:
# File created by KDE Gtk Config # This is a lie now ;-)
# Configs for GTK2 programs
gtk-font-name="Noto Sans, 10"
(this may or may not apply to your other examples … but its the fix for gtk2 theming, like gcolor2)
is there a way to update the highlight colors to match the kde apps? i have tried systm settings-> app style -> configure gnome/gtk app style -> and it updates the window settings but not the highlight colors.
pretty much all gtk apps (mozilla, etc…) still highlight in green and different than kde.
