I've been monitoring my computer's performance while working on Blender. I'm currently on 2.82a. My machine is running Linux Mint 19.3.
I'm currently rigging a model. While working on texture paint, I notice the ram slowly gets more and more used up. I'm aware that things such as file size and undo steps are using up ram, but it doesn't seem to free up if I were to close Blender.
Is there some setting I might have set wrong in my preferences? Should I try an older version? Is this a known bug?
