sancho I don't understand why does some of gtk application start without dark theme. Is it problem with gtk theme or gtk settings?
sancho I've just noticed that when I switch theme to Plata noir, problem is gone. So it has to be theme fault, right?
Justin sancho If you switched theme and it worked, then yes, it's a theme issue. You can report issues to the theme developer with application names that aren't following the dark mode setting.
sancho [Solved] Forgot to mention something important before, this problem only occurs when app is executed by root. sudo cp -r ~/.themes/(theme folder) /usr/share/themes/
