I am occasionally getting horizontal lines across photos when importing from my Sony A7ii into Lightroom Classic CC. This only occurs when importing RAW files. The lines are not always in the same place, but they appear consistently about 50% of the time. This seems to happen most often with a Sony Zeiss 55mm 1.8 lens. Strangely, if I zoom in and then zoom out of the picture, the lines often disappear. So, I do not seem to be losing pictures, but it is definitely an annoyance, and I am not confident that the zoom in / zoom out trick will always work. Any idea what may be going on?
I have tried different SD cards, resetting camera to factory settings, and cleaning sensor, but nothing seems to get rid of the lines. I am using the latest version of Lightroom Classic CC (7.2) on a MacBook Pro. I am hoping this is not a serious camera issue or a problem with the lens.

The first I would try is to deactivate the GPU support.

When you open the RAWs in another program it look's ok?

This is a corrupted photo. The corruption comes from a hardware malfunction somewhere. You need to try transferring to your computer using different hardware to see if you can isolate the problem.

I tried turning off GPU and different cards and readers, but I am still getting these lines. This is ONLY happening with Lightroom Classic CC. If I use Bridge, the sony import software, open in Photoshop, or even just use Lightroom CC (non Classic), the images open without any lines. This only seems to happen with one lens (Sony Zeus’s 55mm f/1.8). Is it possible that there is an issue with the lens? Or is there something I’m missing in Lightroom?

It could be that this is a corrupted preview file, as zooming in and zooming out usually causes an up-to-date preview to be generated and shown. Try selecting a photo and then Library->Previews->Discard 1:1 Previews.

The zoom in / zoom out trick is not working consistently. However, this is only happening with Lightroom Classic CC 7.2, and so far, only with one lens. Using Bridge, Photoshop, the Sony raw tool, or even Lightroom Cloud version, images import just fine w no corruption.

Because those other programs use different previews ... or they don't use previews at all ...
