Sounds like the digitizer from the camera's image sensor that creates the Bayer pattern may have an issue (Bad/cracked solder joint). Usually there is a CPLD or FPGA to convert the Bayer pattern to a usable video stream that is sent to the monitor for reconstitution of what the image sensor "sees".
The problem is figuring out the culprit, the sender (image sensor) or the receiver (LCD monitor) of where the stream is corrupted.
If I had to "guess"....it is most likely the camera itself.....those things are not sealed good from the factory. Our 2019 Serenity has already had the camera replaced due to water ingress...not saying that is what is wrong with yours...but if I was a betting man....replace the camera side of the equation and it all goes away.
