Default [Q] "Low Light" toast notification displayed

Hi, I just got my Nexus 5 and put CM 11.0 M1 on it.

I get a "Low Light" toast notification every time I turn it on (in low light, of course).
I can't help but look at it every time.

Can I turn it off somehow?
I'm not sure if it was there before rooting as I didn't really use it that much.

Thank you.
