Unhappy [Q] Remote control of device does not work?

Hi All,

I do not know if this is a phone or os specific problem. Up to now I've had a rooted Att avail (zte z990). I remote control that screen as needed via any number of vnc like apps. however the same apps - vnc, Smart dog remote desktop (now 3cx) now show a funny screen on my rooted us gsm Moto G (standard rom - just rooted). it looks like mix of stray pixels or perhaps stars. I can click the desktop of the phone but cant see what Im clicking.

Is there a fix for this problem? Is it a kit kat issue or a Moto G issue? How can I fix this - I am not adverse to flashing a custom rom if that is the fix.

TIA
