I am having a similar problem here with the newest Kubuntu (KDE 5.38).
I have the impression the problem is coming from the Slideshow on the desktop,
and my huge monitor resolution. plasmashell uses an incredible amount of 10g of
resident memory on a fresh restart (killall plasmashell; kstart
In the midst of 2017, the memory leak still exists...
I'd like to help you, if I can.

I also see this memory leak with the nvidia driver v346 and the nouveau
driver as well, so no real difference here for me.
What we probably need is a backport of these two patches mentioned in
this KDE bug report:
https://bugs.kde.org/show_bug.cgi?id=344879#c122
otherwise plasmashell will

Update:
if i switch to proprientary nvidia driver (v361, GT430) - then memory NO leak,
if i switch to noveau - then memory leak.

Holy shit !
I confirm that it seems to have solved the issue here too. I switched from
nouveau to nvidia 340 for my GeForce 8400 GS, and now, the memory seems to have
reached a stability point (for me between 280-340 MB).
Thanks !

Yeah, plasmashell is too big a beast to ever work without issue.
Breaking it up into smaller apps would help a lot.
BTW, I added a valgrind log of an idle plasmashell, which is using ~15%
CPU, and increasing its memory usage by ~4MB/min
** Attachment added: "Valgrind of an idle plasmashell"
I see something similar. After 12h running without any action on my part
(during the night), plasmashell went from ~130MB of RAM to ~2GB, with a
constant 2% usage of CPU.
