Hello goodnight.In GNOME 44, using dark themes does not affect the FlatPak title bar, it is a clear standard behavior, but even using options like FlatPak -override no effect, exception of the Dark Libadwaita theme in GNOME 43, I hadthe desired effects.
Você conseguiu entender proque não funciona mais? A variable application-prefers-dark não esta mais funcionando, de padrão ela usa cores claros. E para aplicações de Flatpak fica assim agora.
I suspected as much; the titlebars of all Electron-based applications appear to be GTK4 windows now; not GTK3.
Better report to the applications you have troubles with (Visual Studio Code). So that they actualize the application-prefers-dark variable to the correct/new way. You can link to the discussion here …
