ii kde-config-updates 6.7.4-1
ii plasma-discover-backend-fwupd 6.7.4-1

Versions of packages plasma-discover suggests:
ii plasma-discover-backend-flatpak 6.7.4-1
pn plasma-discover-backend-snap <none>
-- no debconf information
Discover becomes unresponsive immediately when entering any view that displays
applications from the PackageKit backend, including Home and application
categories.
Views which do not display PackageKit application resources remain usable, e.g.
Settings, About, wallpapers/add-ons. Starting Discover directly in Updates mode
also works:
plasma-discover --mode Update --backends packagekit
However, navigating from there to any view which renders PackageKit-backed
applications freezes Discover.
The problem is isolated to Discover's PackageKit application path:
pkgcli search kate works
pkgcli refresh works
pkgcli list-updates works
appstreamcli search kate works
Discover works normally with flatpak-backend,fwupd-backend,kns-backend
Discover freezes when PackageKit-backed application entries are displayed
reinstalling plasma-discover, packagekit, and libpackagekitqt6-2 did not change
the behaviour
A live GDB backtrace taken while Discover is frozen shows the main/UI thread in:
kimg_jxl.so
QImageReader::size()
QPixmapIconEngine::bestMatch()
QPixmapIconEngine::actualSize()
QIcon::actualSize()
libKirigamiPrimitives
Several worker threads are simultaneously waiting inside libjxl_threads.so.0.11.
strace consistently shows Discover opening Debian AppStream JPEG XL application
icons immediately before the freeze, e.g.:
/var/lib/swcatalog/icons/debian-forky-main/128x128/video-downloader_com.github.unrud.VideoDownloader.jxl
The same JXL image opens successfully in Gwenview, so the image itself can be
decoded normally outside this Discover/Kirigami path.
Best,
ThB
