After the last update the weather system no longer works well for me, I do not use any addon or have made any modifications, it was after the update.
I downloaded and installed it again and the problem was not fixed.
The clouds flicker and the frozen silhouette remains blinking even if you move the camera and change cameras.
Okay, best of luck! I am going to merge this topic into the larger topic about this so the conversation stays in one place.
I really hope the workaround works for you!
