Drag and Drop Component and Canvas - scene.pick is not working

i have canvas wrapped in drag and drop react component,

when i call scene.pick onDrop of react component is giving wrong pickedpoint.

is there any thing i have to get the correct value

This is really hard to tell without a repro as lot of thinks could go wrong, First you could try using a setTimeout() or equivalent to double check if it is related to the render not being done for instance ?
