Hello,
I disabled some of my cpus by : ` sudo chcpu --disable $(echo {16..19} | sed 's/ /,/g')`
But the "Individual core usage" is still show the disabled cpus's usage, I think when these cpus are disabled, the widget should not show usage for these disabled cpus.

Thank you for the bug report!

However Plasma 6.3.6 no longer receives updates or maintenance from KDE; active versions are 6.4 or newer. Please upgrade to an active version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one.

If you need help with Plasma 6.3.6, please contact your distribution, who bears the responsibility of providing help for older releases that are no longer receiving updates from KDE.

If you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report.
