After making a test on VM it seems that bug only happens on Fedora 40,, but not on Fedora 41

Comment 6 Nicolas Fella 2025-02-14 14:43:06 UTC

That was testing with a live 40 system, which has a very old Plasma.

On an up-to-date 40 it still does not work, but there Spectacle doesnt even offer recording.

Trying to record with OBS Studio prints

Feb 14 15:40:07 vbox xdg-desktop-portal-kde[1658]: xdp-kde-screencast: zkde_screencast_unstable_v1 does not seem to be available

Comment 7 Nicolas Fella 2025-02-14 15:59:43 UTC

This is caused by Fedora 40 having too old Pipewire for KWin 6.3. It should be fixed in Fedora soon
