Globe Rendering bug with planets other than EARTH

[MuhammedKalkan]

There are rendering issues like flickering and going full dark after that (Ceres / Vesta / Moon).

Or when you zoom out planet turns entirely black (Mars).

Mercury has black going tiles at the edge of the planet (Mercury).

There was no issue with my previous Cesium version which was 1.36

Thanks for reporting this @Nymria ! Are you able to test with any versions between 1.36 and 1.61 to help us narrow down when this issue started? An easy way of testing older releases is using these release links:

https://cesiumjs.org/releases/1.45/Apps/Sandcastle/index.html?src=Offline.html

So that would give you a hosted CesiumJS 1.45. It would also help to post a reproducible code example. For example, is it the custom ellipsoid you're using that causes the issue? Do you have a custom terrain provider? etc.

Hello @OmarShehata

I have narrowed it down to version 1.50. The rendering is broken @1.50 but working on @1.49.

I am using custom ellipsoid and custom terrain provider since this is a different planet.

You can see the sandcastle examples below

And moreover, i have figured it out , this is caused by

viewer.scene.globe.showGroundAtmosphere=true;

When i turned it off then , VOILA! It is working and rendering as expected.

Broken Version 1.50

Previous Working Version 1.49

Ah, thanks for debugging this and posting your result @Nymria ! It looks like you've stumbled on this issue here #7124. I'm going to close this and add your discovery that it broke somewhere in 1.50 there.
