After recent OS updates Chromium stopped does not use Dolphin as file manages by default on file save. Uses ugly gtk one. Issue similar to this one: https://unix.stackexchange.com/q/649910/182014.
plasma-browser-integration
and
xdg-desktop-portal-kde
packages are installed.
xdg-mime query default inode/directory
returns org.kde.dolphin.desktop,
GTK_USE_PORTAL
is set to 1 - nothing helps. What was broken and how to fix this?
Just rollback or wait, Plasma 5.26.1 update to 5.26.2 did broke also wallet autoopen and did ask password. Also Vivaldi “Save” dialog is in GTK style again too. As couple weeks ago.
