I applied one of Zorin's themes to flatpak apps, and some (I assume with newer gnome versions) have padding issues around window buttons. Any ideas how to fix it?
Is it only GTK4 apps showing this?
In GTK4, much of the widget management has been removed entirely from the theme .css control and transferred to LibAdwaita, which keeps its own hidden .css that cannot be seen or modified. LibAdwaita then injects this into the application, styling it according to Gnome's desires.
For GTK3 apps, you still have the accessible styling in the built widgets and bypassing LLibAdwaita can take effect. On GTK4 apps, there is no widget styling built there... only LibAdwaita.
It is how Gnome completely seized control.
Not sure. It happens to Flatseal, Gradia, and Extension Manager from what I've noticed. Bottles doesn't even apply any themes I specify in env variables using Flatseal, don't know why. Gnome's document reader applies the theme and doesn't have window button glitches. All are flatpak apps I installed today or yesterday, so should be the latest versions.
All of these Flatpak's are GTK4.
Some apps make different calls for widgets, so the effect can be less or more pronounced depending on the app.
