Using the three.js editor https://threejs.org/editor/
- create a cube and scale to
100*1*100
- create another cube and scale to
50*1*50, set position y to 0.1
So it should looks like this
But when I rotate & scale the scene, something weird happened
Could someone explains this?
I assume it’s related to precision limitation?
Yes, that happens because of the limited precision in the depth buffer. If you move the camera further away, the problem gets even more obvious.

As @Mugen87 pointed out it is an precision issue of the depth buffer also called z-fighting. By using a logarithmic depth buffer (you can enable in the render options) this issue will be reduced drastically.
