Stats Window shows Render Textures in Unity Free

I have a project running in Unity Free.

It goes without saying, Render Textures are not allowed and hence have not been used.

Why does my stats window show Render Textures?

It’s not bugging me particularly, but I noticed it a while ago. I thought I’d run into the answer given some patience but have not done so.

RenderTextures are used in Unity’s own editor interface, so you’re probably seeing usage due to things the inspector is showing.
