Do you have your wallpaper set to slideshoe?

Massif snapshots of the plasmashell.

Hi guys.
I happen to have an exactly the same problem, and yes, I do change wallpapers.
Actually I've made some measurements while changing them (and then resting for a while) with the Massif tool (valgrind).

Could you please have a look? I've tried to do a research but I know too little about how Qt handles graphics so it's not that obvious for me. Having said that, it's still pretty obvious that a memory passed to nvidia libgl (in my case) is never freed.
