CPU usage y-axis go above 100% STEPS TO REPRODUCE I am not even sure how it get like this, it appears to happen randomly. OBSERVED RESULT CPU usage y-axis go above 100% and went to 800%. This make the CPU usage look flat because it is so small. EXPECTED RESULT The CPU usage should not go above 100% I install system monitor from here: https://build.opensuse.org/package/show/KDE:Frameworks5/plasma5-systemmonitor System monitor 1.0 Operating System: openSUSE Tumbleweed 20201105 KDE Plasma Version: 5.20.2 KDE Frameworks Version: 5.75.0 Qt Version: 5.15.1 Kernel Version: 5.9.1-1-default OS Type: 64-bit Processors: 8 × Intel® Core™ i7-3770 CPU @ 3.40GHz Memory: 7.5 GiB of RAM Graphics Processor: Mesa DRI Intel® HD Graphics 4000
Created attachment 133131 [details] CPU usage y-axis go above 100%
Update: It seems that 800% CPU on y-axis is not an issue, the issue is that the CPU usage is shown as 0%. Try using ksysguard which show CPU usage properly. I upload a new screenshot showing system monitor on the left and ksysguard on the right.
Created attachment 133132 [details] ksysguard show proper CPU usage while system monitor does not.
Was this reported twice, here and 428822?

The 800% value is because the chart is stacked so each individual core is added up. Since each core ranges from 0 to 100% and you have 8 cores you end up with 800%. We solved this for the process/applications table by having a way to display values normalized to 100%, we might want to do something similar here but that's a bit more tricky. As to why it is showing only 0%, that one is a bit more odd as the sensors use the same data source. Does the "CPU" chart on the overview page work correctly?

I will have to wait until CPU usage is 0% again because I reboot my PC and its fixed, it happen randomly for some reason.

Thank you for helping us make KDE software even better for everyone!
New information was added with comment 8; changing status for inspection.
Just for future refrence, if one prefers the way it is displayed in ksysguard they can uncheck "Stacked Charts" and lower the "Fill Opacity" in the chart settings.
Seems like this is resolved now, if you encounter it again feel free to reopen or file a new bug.
