I have also the same issue and tried removing all widgets and reverting the theme back to Breeze before coming to your bug report.
Changing the wallpaper to solid colors really did fix it for me also.

OBSERVED RESULT
plasmashell memory leak when using pic of the day: astronomy.

I think that maybe under "KDE/kdeplasma-addons/blob/master/dataengines/potd/apodprovider.cpp" at pageRequestFinished there's a missing return statement at the end, but I could be wrong.

Comment 4 David Edmundson 2019-10-24 14:37:16 UTC

missing where?

Comment 5 Daniel Biagi 2019-10-25 01:55:24 UTC

Nevermind, at least for me it was fixed after today's update

Comment 6 Andrius 2019-10-25 18:04:04 UTC

Still the same for me

Comment 7 Andrius 2019-10-25 18:06:21 UTC

Strange: when I first set the wallpaper as "Astronomy Picture of the Day", RAM and CPU spikes for a minute or so, but then drops to normal.
