Flickering in Debug View

[haxybaxy]

Hello!
I am trying to detect Aruco Markers off the floor and I am not able to detect my markers reliably, as the detection marker keeps coming on and off, and when I open the debug topic I am getting something like this:

As you can see the feed keeps flickering and my marker keeps getting undetected when the screen goes all black.
When run my code, it also warns me that normalizeImageIlluminaiton is not implemented.
Is there a way where I can re-enable the normalization to eliminate the flickering? Or can I change something about my environment to make the flickering less?
