Portal doesn’t work (no window show up) until I restart xdg-desktop-portal.service

[ariasuni]

Operating System

Arch Linux

XDG Desktop Portal version

1.18

Desktop Environment

KDE

Expected Behavior

A file chooser dialog appear when I hit Ctrl+S on Firefox and Thunderbird without any specific manipulation.

(also, using Screenshot tool in Firefox works correctly)

Current Behavior

No window shows up when I should have a file chooser dialog. The only way I’ve found to make it work is to restart xdg-desktop-portal.service. I have this problem after every reboot.

(also, using the «Copy» option in the Firefox builtin screenshot tool makes Firefox and the desktop freeze for more than 10 seconds, and only afterward is the screenshot copied to the clipboard)

Steps to Reproduce

1. Install xdg-desktop-portal and xdg-desktop-portal-kde (doesn’t change anything if I have xdg-desktop-portal-gtk installed or not)
2. Put export GTK_USE_PORTAL=1 in ~/.profile
3. Reboot
4. Launch Firefox
5. Try to save a webpage

Anything else we should know?

It works perfectly fine with 1.16.

I have the same issue, but for me obs can't get a desktop and also screen/window picker for streaming won't appear until xdg-desktop-portal service not restarted
Arch Linux, KDE Plasma 6, Wayland+nvidia-dkms

I noticed it works now, not sure if it’s due to xdg-desktop-portal 1.18.2 or xdg-desktop-portal-kde 6.0.3 or a Firefox update or something else.
