"disableDepthTestDistance: Number.POSITIVE_INFINITY" give rise to disappear when drag to some place

[emperorOfBug]

when i use "disableDepthTestDistance: Number.POSITIVE_INFINITY" in a new entity just like this

viewer.entities.add({ position: Cesium.Cartesian3.fromDegrees(-75.59777, 40.03883), billboard: { image: "../images/Cesium_Logo_overlay.png", disableDepthTestDistance: Number.POSITIVE_INFINITY }, });

Then I drag earth and found that billboard twinkled in some place. Then I drag slowly and finally found a place near here that the billboard disappear!

You can move earth and find a position when the billboard twinkled, then try to move it to the very special place.

Hi @emperorOfBug, I'm having trouble reproducing this. Would you be able to provide your system hardware specs?

[emperorOfBug]

Thanks for response. I've tested on three different devices.
It is really difficult to reproduce when the number is 1;
Please append more entities(more than 100), and use "disableDepthTestDistance: Number.POSITIVE_INFINITY", some of them will twinkle frequently.

@emperorOfBug I'm still having difficulty reproducing the issue. Here is my example with a couple hundred entities.

Would you be able to provide and example and the hardware specs that works for you to reproduce the issue?
