Running Debian/Unstable updated this morning I have the KDE screen locker
doing 14ms sleeps on the PinePhonePro:

I also have plasmashell doing 8ms sleeps but also lots of 8 byte read and
writes, strace output scrolling rapidly:

ii plasma-workspace 4:6.2.4-1 arm64 base for Plasma Desktop,
Mobile, and Bigscreen graphical enviro
But the "plasma-settings -m kcm_mobile_wifi" command isn't too bad now. Seems
that the same bug is still there in libraries but being triggered by different
apps. Should we reassign it to plasma-workspace or libkscreenlocker6?
