--- Comment #7 from Patrick Rudolph <patrick.rudolph@br-automation.com> ---
I've noticed this issue on several of out test system. We are using 
plasma-workspace 5.8.6 on Intel Skylake based platforms.

Usually the memory grows a few hundreds of byte per minute.
Sometimes it grows much faster.
No special processes are running, just plain KDE desktop.

The issue wasn't observed on other (older) Intel platforms.
The issue wasn't observed in case the desktop is started on a VNC session.

I noticed that stopping the plasmashell process (using SIGSTOP) stops the
ksmserver memory from growing. I suspect it's some kind of bug in the
plasmashell that only exists on some display drivers.

As the display driver might be related adding some debug infos:
* Mesa
* Vendor: Intel Open Source Technology Center (0x8086)
* Device: Mesa DRI Intel(R) HD Graphics 530 (Skylake GT2)  (0x1912)
* Version: 17.0.4
* modeset driver
