Very high memory usage. Is it memory leak?

My wallpapers are a slideshow from a directory on my second drive (HDD NTFS). When I set the original directory from the HDD as my wallpapers, plasmashell consumes all available memory (31GB peak). However, if I copy this directory to my home folder, everything works fine.
Arch Linux, plasma version 6.2.5

Hi! Could you please share the details from the Info Center app for the system where you’re seeing that behavior? The Copy Details button is the easiest way to paste that into a post here:

There is an existing bug report around memory leaks when changing wallpaper that might have a few different situations wrapped up in it - 480693 – Major memory leak when changing wallpapers - so it might also be helpful to find out:

  • Does memory leak when you just change wallpapers at all, even without the slideshow?
  • If you have an NVIDIA graphics card, are you using the proprietary drivers or the Nouveau ones?

Thanks!
