Comment 1 Bug Janitor Service 2025-07-10 11:58:19 UTC
A possibly relevant merge request was started @ https://invent.kde.org/plasma/libplasma/-/merge_requests/1337
Comment 2 Nicolas Fella 2025-07-10 11:59:20 UTC
Sentry logs say

kf.plasma.quick: error when loading applet "org.kde.plasma.icontasks" QList("file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/main.qml:395:9: Type ToolTipDelegate unavailable", "file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/ToolTipDelegate.qml:72:9: Type ToolTipInstance unavailable", "file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/ToolTipInstance.qml:312:30: Type GE.DropShadow unavailable", "qrc:/qt-project.org/imports/Qt5Compat/GraphicalEffects/DropShadow.qml:6:1: Cannot load library /usr/lib64/qt6/qml/Qt5Compat/GraphicalEffects/private/libqtgraphicaleffectsprivateplugin.so: /lib64/libQt6ShaderTools.so.6: undefined symbol: spvValidatorOptionsSetAllowOffsetTextureOperand")

so this looks like an ABI issue in Fedora.

https://invent.kde.org/plasma/libplasma/-/merge_requests/1337 should make it not crash and more gracefully show an error though

Thanks Nicolas!

With that changed, what's left here is a distro issue, so I'll mark this as RESOLVED DOWNSTREAM.
