👍️ . For testing the applications you can enable gtk debug
gsettings set org.gtk.Settings.Debug enable-inspector-keybinding true
GTK_DEBUG=interactive your-app-name (in terminal)
(Hope you have libgtk-3-dev in ur system)
gtk debug you can change css permanently so take backup before changing
so you can test all the apps look and feel in your theme.
and check the workspace switcher it is always black color and the preferences settings are deprecated.
(gsettings set org.gnome.desktop.wm.preferences theme Arc-Dark )
send us your git link so we also can test in our end
