New K8600 with some LED flickering

hi
I just completed the whole installation and doing my first print, but what noticed me, is that during printing, the LED strip VERTEX sometimes it looks that it blinks, not completely off, but kind of dims a couple of time very quickly, I dont see any relation between the action he is doing at that time, and during standby its not doing that.

everybody else has this same thing?
