You will want to change the Target of your Repeater Region. The problem is that the Target includes the active foreground window on more than one PC, so both of them are sending competing position updates -- you move the mouse, the other PC sends a previous position, and then your mouse rubber bands. Make an Action Target Group (ATG for short) for the Character this is going to: right click Action Target Group, select New, name it like "healer", drag Character to it, Export) and then it will be selectable in the Repeater Region creator area in-game. Kill the old region (or click Clear to clear all if you made multiple), click Block Local Click and select the ATG for the healer, then click Add and position the new Repeater Region.
Tip: Be careful about the size of your Repeater Region, because clicks will be passed through the whole thing; If you click outside of the unit frames but inside the Repeater Region, you may cause your character to move, etc.
