Wtf is going on w my screen/camera?

Florescent lights? I've seen things like that happen when taking pictures of old CRT TV's and computer screens. I have to admit though, that looks like it could be a hardware issue, since I've not seen a camera out of phase with the lights in a long time (they should adjust automatically, at least my Note 5 adjusts to the phase even with my LED Christmas tree that has a noticeable "pulse" to it)
