No save button or location bar in save file dialog

[RaviRahar]

I don't quite know what the problem is yet. But I do not get a save button or location bar. I am unable to save files. Open button does not appear neither. I am on hyprland arch linux (hence wayland) and tried both xdg-desktop-portal-gtk (version 1.15.1-2 built on 22nd April) and xdg-desktop-portal-gtk-git. xdg-desktop-portal-lxqt is working correctly.

$ cat ~/.config/xdg-desktop-portal/portals.conf
[preferred]
default=hyprland;gtk
org.freedesktop.impl.portal.FileChooser=gtk

$ journalctl --user -u xdg-desktop-portal-gtk --no-pager | tail -n 9

The problem was gtk applications hide header bars when in fullscreen mode. And I was forcing all apps to be fullscreen.

# If you know hyprland, I was using fake fullscreen. Now I added these applications to exception:

windowrulev2 = fakefullscreen, class:^(?!gimp|xdg-desktop-portal.*)(.*)$
