Styling not working for Libre Office and Gnome System monitor

[dccoder84]

Hi,

thank you for developing this nice app :) I successfully changed title bars and menus for my GTK 4 apps. But I don't understand why the styles don't apply to the Gnome System Monitor and Libre Office Writer. What is the reason to this?

Regarding Libre Office Writer I can install different debian packages for it. They are called libreoffice-gtk3 and libreoffice-gtk4. When using the gtk4 package (and forcing it with the environment variable SAL_USE_VCLPLUGIN=gtk4) the menus of libreoffice writer have the typical gtk4 look with rounded corners. But unfortunately they are not affected by the theming from Gradience. The same goes for the Gnome System Monitor. Can anybody advise?

Many thanks in advance,
