SUMMARY switching activity leaks shared memory segments. STEPS TO REPRODUCE 1. Login, set up activity pager and several activities with different backgrounds 2. use ipcs -mp | wc to see how much shared memory is in use 3. switch between activities and back 4. You will see the shared segement count goinging up about 10 segments for each two switches.

The workaround is to kill and restart plasmashell. I use kill <pid>; kstart plasmashell & this spews out many messages - a cleaner restart would be helpful, but this does the job.
How is this related to the 'Active Window Control' addon?

Thanks for the update; changing status.
Moved to plasmashell/pager as this doesn't happen with the default activity switcher.
hmm, I tried all the activity switchers that I could find, and they all exhibit a similar problem. Which activity switching mechanism did you use which didn't please? One of them seemed to waste less memory, which is good, and has a smaller panel footprint which is very good.
