I've been experimenting with my OAK-D for several months now, running various example scripts unmodified, and a few scripts of my own, mostly derived from the examples with modifications to support my goals. I've noticed that when viewing the ColorCamera isp stream, I see something that is difficult to describe, but visually appears that something moved the camera forward and then backward (or maybe backward and forward). I know for sure that there is no mechanical motion as the camera is firmly attached to an immobile object. The phenomenon lasts probably less than a second, and seems to happen at unpredictable intervals on the order of minutes.
I've only noticed the behavior with the color camera, but it may happen with the mono cameras as well.
Could this be a power issue? I'm powering the camera currently with just the USB cable from my MacBook Pro. But I remember seeing the phenomenon even when I first started experimenting and also had the power adapter connected.
Is this behavior expected, or am I unlucky? Is there anyway to investigate further in order to fix it?
