Description Edward Kigwana 2021-10-30 16:23:16 UTC 
SUMMARY

no-icons-only task manager and not switcher either

STEPS TO REPRODUCE
1. Start plasma on x11

OBSERVED RESULT

Small block on task bar indicating failure to load with message copy cause

file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/main.qml:400:5: Type ToolTipDelegate unavailable

file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/ToolTipDelegate.qml:80:9: Type ToolTipInstance unavailable

file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/ToolTipInstance.qml:184:17: TaskManager.PipeWireSourceItem is not a type


If I comment out just the pipewire section from plasma-desktop/applets/taskmanager/package/contents/ui/ToolTipInstance.qml on X11 I get an Icons-only task manager again

The change that caused the breakage for me was https://invent.kde.org/plasma/plasma-desktop/-/commit/238a076c8d9d80f874f3cbef7ba857db7efda7ac

I assume you're compiling from source or using git master packages? I am as well, and I don't see this. Can you update the system or recompile and try again?
Comment 2 Fushan Wen 2021-11-01 15:58:50 UTC 
in plasma-workspace/libtaskmanager/declarative/taskmanagerplugin.cpp

#ifdef WITH_PIPEWIRE
    qmlRegisterType<PipeWireSourceItem>(uri, 0, 1, "PipeWireSourceItem");
    qmlRegisterType<ScreencastingRequest>(uri, 0, 1, "ScreencastingRequest");
    qmlRegisterUncreatableType<Screencasting>(uri, 0, 1, "Screencasting", "Use ScreencastingItem");
#endif

I misunderstood that. PipeWire could be still unavailable. Will push a fix to restore the file.

I did with the same results. I think I am missing pipewire runtime dependency or something
