I created several boxes. All of them are instanced from a source box which I have setEnabled(false) to hide it.

**When I pan the camera left and right** the boxes “glitch” in and out. They disappear and then reappear depending on the camera angle.

All stacked boxes are the same height, in the screenshot above, you see some instances become momentarily “clipped” as you pan the camera over them.

Is this a bug or am I doing something wrong? I’m viewing the playground using a macbook pro running Chrome browser. Update: Issue also happens on Firefox and Safari.

Here is a link to the playground: [https://playground.babylonjs.com/#JUH9FA](https://playground.babylonjs.com/#JUH9FA)
