For a while in our application, we have been experiencing a mysterious black dot appearing in the upper third of our screen. It seems to stay in the same place regardless of the direction of the camera, but it can be occluded if there is a Cesium entity in front of it. It changes shape slightly, but seems to consistently affect two or so rows of pixels on the same area of the screen.
Does anyone know what might be causing this? It has been vexing my team for quite some time now, and we can’t figure out where it is coming from.
Here it is appearing in the sky
Here it is slightly obscured by some semi-transparent walls.
Any advice you might have would be very helpful!
