A notch filter is only applied to luma, never to chroma (it would eliminate the color signal from the color circuits!). So, you are seeing the expected effect with a notch filter set, with luma in the color bandpass showing as flickering color.The short shutter time used for the picture captures one phase of the cross color instead of averaging it out, making it look worse.
In both shots (color on and color off), the black level (don't know if it's labeled "brightness" on this set) is set too low. This makes the darker gray scale chips all look black, and may have prompted the chroma to be turned up too high to bring up the red and blue bars, also increasing the visibility of the cross color.
