I recently got the ROG Strix XG279Q and it's been working great. However, there is this small anomaly I want to check whether or not it's normal behavior.

Once in a while there are parts of the screen that flicker/flash white. Like a white band on a quadrant or half of the screen. Very briefly and rarely. When I say rarely it's like hours can go by without me noticing anything, and then maybe a get a couple of flashes within the next half hour or hour.

Now, I don't mind it at all as long as it's normal and not a faulty display. Hence my question. Should I be concerned or just forget about it?
