Question

Heavily pixelated clouds in previews

This is happening for quite some time. Looks like a regression that was introduces in one of the recent versions. When in library mode, clouds in previews are pixelated. Clicking and zooming in loads the photo updates the preview but it is annoying zooming in and out every time. I noticed that this is happening with clouds only - the rest of image looks more or less normal. Does anybody experience the same and how to handle it?

    I am seeing the same problem as you. I shoot with a Nikon D850 and the Library previews sometimes (not always) show pixellation in the skies/clouds. Changing zoom values usually clears the problem. Very annoying. I think I started seeing this problem when I upgraded my macOS to Mojave, but I am not 100% sure.

    The only variable in my case is LR - I am on the same Windows version for a few years already. I see this artifact rather consistently - one photo or another but it is almost always there. Just opened LR and photo that was shown yesterday without pixelation has it now. I was wondering if Adobe support (or developers themselves) monitoring this forum - I tend to think it is a bug on their side.

    All I can suggest is to generate 1:1: previews on Import.

    What type of camera took the image? What is the pixel size of the image? Raw or JPEG? What version of Lightroom?

    Since it's that large of an image, it doesn't appear to me that it's in focus or properly exposed. Probably handheld. That appears to be a lot of color noise in the clouds. Perhaps a tripod would have helped. I know, I'm not being much help here.
