Of greater concern: it looks like 6.8.0-40-generic is the kernel showing this graphics issue. I mistakenly fixated on the “patch” version, in [kernel].[major].[minor]-[patch] numbering terms.
Now my “resolved” in title is quite misleading. Maybe I should make a new clearer question thread.
6.5 issues?
From /boot/grub/grub.cfg:

What issues were others reporting? Best to search discuss.kde.org, or bugs.kde.org?
I’m noticing issues waking from sleep, and non-interactive (including pty switching) on waking from sleep, with 6.5.0-45.
