Package: kde-spectacle Version: 6.3.4-1 Severity: normal Screencasting does not work with spectacle, it doesn't matter what format you choose, it won't work. Journalctl results in 'Failed to export video: Temporary file URL must be an existing local file'. The same error message is produced on the GUI as soon as you terminate the video recording. kde-plasma-desktop was installed in an attempt to install KDE on a fresh Debian trixie install.
Coincidentally, even the thumbnails preview in taskbar is not working -- the root cause maybe the same, because both use pipewire. Both of these features work with KDE neon live CDs suggesting a package build configuration issue. Hint -- This is seconded by the fact that I've been facing similar issues on Gentoo (where the build configuration is equivalent to USE configuration) where screencasting and thumbnail preview is not working only for my setup. There are plenty of Gentoo users for whom it's working, each of whom have different build configuration. Discussion: https://forums.gentoo.org/viewtopic-p-8856252.html
