Do I need to ground my composite video signal?

I modded my fpv goggles and installed a diversity 5.8 GHz receiver module. I am powering the LCD screen and the receiver module from separate linear step down regulators. Both are being powered from the same battery. I am having some issues with video quality and I cannot figure out where it's coming from. Ive completely went trough the entire video system on my fpv quad copter and still no change.

I was wondering if I should run a ground wire from my receiver module to the LCD driver board. Since both are being powered from the same battery and all the grounds have continuity with each other I don't think that would help or would it?
