Hi everyone!

I am trying to add a right-click menu, but I got a weird problem:

1. I click on scene, and scene.pointerX/Y can get coordinates of cursor in pixel unit;
2. Although it’s not integer due to [Why are scene.pointerX and scene.pointerY not integers? - #7 by wulf11](https://forum.babylonjs.com/t/why-are-scene-pointerx-and-scene-pointery-not-integers/43547/7), but I think it doesn’t matter;
3. I create a container with the XY (container.left=X…) but container wont show near my cursor
4. the more cursor off the scene center, the more container shift away cursor.
5. The XY i got is correct, i have calibrated on the corner of scene, and compared with canvas size.
6. the funny thing is I cannot reproduce it in playground…

Here is a screenshot: I hardcode container at (1000px, 500px), and red point is where scene.pointerX, Y equal to this value.

Can you please give me some advice how to debug this?

Sorry for this confusing question…

Bests,

Although I hear that the issue doesn’t repro in the playground, could you provide one anyway that shows what you’re trying to do? It would help with debugging. Thanks!
