Version: 6.3.3
Platform: Manjaro
OS: Linux
Status: REPORTED

Screenshot of a side by side comparision between htop showing 20 cores and the
system monitor showing 4
SUMMARY
On my Tuxedo laptop I have two profiles, one for battery use that enables 4
cores and one for tethered use that enables all 20 cores, during Startup my
laptop was in battery mode so it was 4 cores when I started the plasma session,
a few hours later I noticed that thunderbolt did not charge my laptop so I
unplugged and plugged back in, that switched thunderbolt mode to enable
charging and thus the Laptop switched to the tethered profile enabling all 20
cores
STEPS TO REPRODUCE
1. start pc with some cores disabled
2. enable some additional cores while plasma is running
3. open system monitor to look at cpu graphs
OBSERVED RESULT
it shows 4 cores in the history view
EXPECTED RESULT
it should show 20 cores like htop does
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 6.12.19-1
KDE Plasma Version: 6.3.3-1
KDE Frameworks Version: 6.3.3-1 I believe
Qt Version: 6.8.2-3 I believe
ADDITIONAL INFORMATION
I'm using the tuxedo control center to edit my profiles but I'm sure this can
be achieved through more universal means
Also I have a system monitor sensor widget in my task bar, maybe that is
keeping something alive
