I can confirm this and also running V1.
It'a called: Pixel-Walk
From what I read, most cheap 6bit TN and IPS panels have similar results. The AUO B173HW02 V1 is 6bit.
"This is not a problem on it's own as the PWM frequency is always high enough that the human eye can not perceive it. The problem is when this frequency or it's harmonics are close a frequency of the LCD, patterns will be created in the light intensity called beat patterns. Since these beat patterns are dependent on the absolute frequency of the LCD and LED PWM, and since each GPU and the LED PWM are sourced from different clocks, the issue will be different for every motherboard, and will vary with such things as voltage and temperature."

It's inherit by cheaper hardware component control and calibration.
