Pixelated and grainy clouds are back starting with 1.14.5.0

The old issue with pixelated and grainy clouds is back (see screenshot below).
It was definitely improved with the last World Update 3, very nice clouds. But then we had the outline against clouds and objects.
Now, with Sim Update 3, the outlines are fixed, but the pixelated clouds are back again. Maybe there is any correlation :thinking:
