My camera has some kind of physical problem. It's with the RGB sensor. RGB sensor was always noisy, but the noisiness is now getting stronger and stronger. It's so noisy now that it's almost impossible to recognize features by RGB. The noise is mostly blue-lines moving over time. The depth sensor is OK.
I've recorded a screencast here:

I've tried it in multiple computers and multiple USB ports. The result is the exact same noise.
