--- Comment #3 from Peter_H <pha...@gmail.com> ---
So I have cleared out my Home folder on Arch Linux to try with a fresh KDE
config for a longer period of time. This has been working better than before,
at least from a KDE perspective.

I have hade issues with Konsole and Gwenview not starting. There is no coredump
generated, and trying to start the software in question through Xterm has
printed some failure in loading a shared library (.so) file. Reboot has fixed
this, and sometimes if I knew what package I could reinstall the package and it
would be solved.

I have had some wierd crashes in other software not related to KDE as well,
like wine and conky.

So I'm back into thinking this is some hardware issue, creating crashes with
some random bit-flips/read error. But Memtest86+ still does not report any
errors. What is the most likely hardware to cause an error like this? Read
error from NVME? or broken CPU bit-flipping, or broken RAM?
