Application: plasmashell (6.2.2) ApplicationNotResponding [ANR]: true Qt Version: 6.8.0 Frameworks Version: 6.7.0 Operating System: Linux 6.11.5-1-default x86_64 Windowing System: Wayland Distribution: "openSUSE Tumbleweed" DrKonqi: 6.2.2 [CoredumpBackend] -- Information about the crash: When attempting to edit a System Monitor widget on a panel, removing a sensor will cause plasmashell to crash. Example: System Monitor widget set to monitor CPU values (custom options selected - not default). Style set to Text Only. Under sensor details if I attempt to add/edit and save a sensor that I have added it will allow you to "OK" or "Apply" or "Cancel" the changes you are making. If I attempt to remove a sensor by clicking the red X next to the sensor the configuration window freezes and does not allow any edits to be made. This is due to plasmashell crashing as reported by the Crash Handler. I have tested this with other sensors I have set up to monitor different system resources (GPU, Memory, Network) and the end result is the same. The crash can be reproduced every time. -- Backtrace (Reduced): #4 0x00007f46b82c8790 in QSGThreadedRenderLoop::windowFor (this=0x55a1ffeccc90, window=0x55a20266d330) at /usr/src/debug/qtdeclarative-everywhere-src-6.8.0/src/quick/scenegraph/qsgthreadedrenderloop.cpp:108 #5 QSGThreadedRenderLoop::maybeUpdate (this=0x55a1ffeccc90, window=0x55a20266d330) at /usr/src/debug/qtdeclarative-everywhere-src-6.8.0/src/quick/scenegraph/qsgthreadedrenderloop.cpp:1409 #6 0x00007f46b804ff51 in QQuickItemPrivate::dirty (this=0x55a21c6cfe40, type=QQuickItemPrivate::Position) at /usr/src/debug/qtdeclarative-everywhere-src-6.8.0/src/quick/items/qquickitem.cpp:6743 #7 0x00007f46b8057660 in QQuickItem::setPosition (this=0x55a21c6cfd50, pos=...) at /usr/src/debug/qtdeclarative-everywhere-src-6.8.0/src/quick/items/qquickitem.cpp:7256 [...] #9 0x00007f46b712cab5 in QGridLayoutEngine::setGeometries(QRectF const&, QAbstractLayoutStyleInfo const*) () from /lib64/libQt6Gui.so.6 Reported using DrKonqi

Cannot reproduce the issue with those steps.
I can't get my system to freeze, but it certainly is super slow. 1. Add empty system monitor sensor to panel 2. Set it to text only 3. Go to sensor details 4. In sensors, click CPUs, [Group] CPU, [Group] Total Usage (%) 5. Click ok 6. Open settings again 7. Remove one sensor from the sensors list This is where plasma for me has a noticeable slowdown, but only if I remove the first item in the list. The last item doesn't have slow down. I have 12 core total usage sensors in total in mine. The less items there are, the less the slowdown lasts.

Remove one sensor from the sensors list Thanks for your for your precise steps to reproduce. I have been griefed by this exact issue a couple of weeks back, but I cannot reproduce it anymore, neither on Plasma 6.3.4 (KDE Framework 6.14.0) nor on development version, Plasma 6.3.80 (both KDE Frameworks 6.14.0. Seems to be fixed for me. To the design and devs: The customizability and intuitive design btw is amazing. Great job.
Looks like it's fixed, closing.
