[Debian-on-mobile-maintainers] Bug#1073294: more information for comparing with KDE6

[Russell Coker]

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

ppoll([{fd=4, events=POLLIN}, {fd=18, events=POLLIN}, {fd=26, events=POLLIN}, 
{fd=27, events=POLLIN}, {fd=34, events=POLLIN}, {fd=35, events=POLLIN}, 
{fd=37, events=POLLIN}, {fd=38, events=POLLIN}, {fd=39, events=POLLIN}, 
{fd=141, events=POLLIN}], 10, {tv_sec=0, tv_nsec=14000000}, NULL, 8) = 0

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

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?
