Is it worth to shield short wires?

by short i mean arround 3cms..

After proper shielding the PPM wire from the PPM encoder to the OSD , im still having problems with interference in the OSD control chanel (provocating switching of screens and unwanted changes between flight modes)..

Left is the 3 wires that go from the RX to the PPM encoder (to carry 7 channels) wich now are arround 15cms long and twisted..

to eliminate chance of RF noise coming throught there i wanted to shorten them down to just 3cms as the PPM encoder is right next to the Rx..
but i wonder if its worth to shield just 3cms as it would have 1-2cms of unshielded part for each side

This was the farthest i dared to go for now
