Hello! I'm getting these resolution issues on LightRoom mobile, but the same thing happens on desktop. On desktop, the fix is to zoom in, wait a sec, let it clear, then zoom out. It clears the ripple effect but it's just temporary. If I'm on mobile, there's no fix to it and when I export to my phone, the image isn't crisp and the ripples show. Does anyone know how to resolve? A screenshot is attached. It looks like the ripple effect from throwing a rock into a pond.

 

Thanks so much.

In Develop module, at 1:1 or greater, do you see it? 

Zooming out subsamples the preview data and it isn't unusual to see a moiré pattern depending on the image. That is simply the downside of zooming out.

This looks like banding caused by jpg compression, which happens typically in flat areas, like a clear sky.

To avoid it (or at least minimize it), the image has be saved (or captured) with a high quality jpg setting.

It can also happen after saving a jpg more than once. Jpg is a final format, and not suited for editing. Every time a jpg is saved, image quality will deteriorate.
