rpm -qa | grep plasma output

I run Leak 15.5 with KDE on my laptop with 8Gb of memory


When i run in a window "watch ps v k-rss -p pid-of-plasmashell" and i confire my desktop to run a slideshow as wallpaper, on each new slide i can see plasmashell grow.

I normally keep logged in and just suspend my laptop when i'm not using it, so plasmashell is rarely stopped. At startup it uses about 4.5% of memory, but i'v seen it use 76% when i logged out just to kill it.

I'm running with plasma5-workspace-5.27.9-bp155.2.3.1.x86_64 which provides plasmashell, but searching the web i find very old mentions of this bug so i suspect this has been an issue for a very long time (oldest was from 2018)

You can reproduce this by having a folder with some pictures, configure KDE to slideshow them (right click on the background) and set the frequency to 1 second.
Then watch the ps command reporting a growing plasmashell.
