What you did

While upgrading my project to bevy 0.19 I've noticed it's become impossible to remove atmospheric rendering from a camera. When the AtmosphereSettings are removed from the camera, the scene starts flickering pretty badly. I reproduced this in the example as well.

What went wrong

In bevy 0.18, I could disable the atmosphere by deleting the previous component and it worked as expected. In bevy 0.19, flickering appears. The flickering seems to encode a visual "atmosphere" state that then does not get updated when moving the camera, the state seems to get baked in at the moment I remove the AtmosphereSettings
