How to reproduce: ``` $ sleep 2; qdbus org.freedesktop.ScreenSaver /ScreenSaver GetSessionIdleTime 0 ``` It seems to work properly when using Plasma (X11) session. Using Fedora Kinoite (latest, as of 2022.02.02). - KDE Plasma 5.23.5 - KDE Frameworks 5.90.0 - Qt 5.15.2 - Kernel 5.15.18 - Wayland (amdgpu) Thanks in advance for any help.
This bug makes some applications work buggy. E.g. if I don't use computer for a while, Telegram should stop marking messages as read and start sending notifications even there's opened chat. That doesn't happen due to the bugged response. Telegram's auto-lock feature doesn't work as well.
ScreenSaver service is provided by kwin_wayland on wayland session. The return value comes from kwin's own kidle time implementation, which is at https://invent.kde.org/plasma/kwin/-/blob/master/src/plugins/idletime/poller.cpp#L79 We would just need to have a valid implementation for it.

That code is used for stuff inside kwin, kscreenlocker should use kidle integration provided in kwayland-integration
