I've solved with a workaround, a Bash script that restarts plasmashell 
every time the screen gets unlocked.

### ### ###

#!/bin/bash

#
# restart_ps.sh : to place under /usr/local/bin/ to restart plasmashell 
executable
# every time the screen get unlocked.
# In KDE desktop add to: Systemsettings → Autostart → Login Script
#

skip=0	# "skip" variable to execute plasmashell executable only once.

dbus-monitor --session 
"type='signal',interface='org.freedesktop.ScreenSaver'" |
while read x; do
	case "$x" in
	*"boolean true"*) : ;; # echo SCREEN_LOCKED;;
	*"boolean false"*)
	if [[ $skip == 0 ]]; then
		skip=1
		/usr/bin/sleep 3
		DISPLAY=:0 /usr/bin/plasmashell --no-respawn --replace >/dev/null 2>&1 &
		# echo SCREEN_UNLOCKED
	else
		skip=0
	fi;;
	esac
done

HTH, kind regards.
