I’m using Transform Controls and my canvas is inside a grid element.
the original `getPointer` function returns
```javascript
return {
x: ( event.clientX - rect.left ) / rect.width * 2 - 1,
y: - ( event.clientY - rect.top ) / rect.height * 2 + 1,
button: event.button
};
```
also I’ve tried
```javascript
return ( {
x: ((event.clientX - rect.left) / (_domElement.clientWidth)) * 2 - 1,
y: - ((event.clientY - rect.top) / (_domElement.clientHeight)) * 2 + 1,
button: event.button
});
```
and
```javascript
x: ((event.clientX - rect.left) / (rect.right - rect.left)) * 2 - 1,
y: - ((event.clientY - rect.top) / (rect.bottom - rect.top)) * 2 + 1;
```
without a chance.
When trying to move my object the transform square when hover changes color with an offset.
It gets worst when the object is far away from 0 position
any idea, please let me know if you need more infos.
Best

Do you mind demonstrating the issue? Offsetting the canvas seems to work for me: [three.js dev template - module - JSFiddle - Code Playground](https://jsfiddle.net/azsk7wmL/1/)

Hi! I’m having the same issue. Did you ever manage to resolve this?

@wenxich Nope, not for the moment.
