Move with Gesture - problem - it Jumps

[carmandale]

I am copying from this wonderful demo - which works well - https://codesandbox.io/s/r3f-train-l900i?file=/src/App.js:3528-3567

and trying to adapt it to work horizontally instead of vertically. I can get it to work for the wheel, just applying it to the X value instead of the Y and it all works as expected. But when I try to change the onDrag. it jumps when you touch the screen instead of staying where it is and continuing smoothly.

this demo shows the same problem - https://codesandbox.io/s/r3f-gesture-camera-for-medium-9br9l?from-embed

it jumps to where your mouse click is. I can't seem to find what is making the first sample "stay put" and be smooth.

thanks,
