Strange lines showing up on pics, only in Lightroom
I've imported a few thousand images to a catalog but some images show up in Library and Develop with bands of random colored lines.
I've tried all the options for graphics processors, no change. Rebuilt previews, no change.
However, if I edit the image in Photoshop or view in explorer the image is fine. It only happens in Lightroom. If you looks closely you can see there is a subtle difference between Library and Develop.
If I export from Lightroom the same lines are then visible in the exported file in any image viewer.
Happens with all image formats, from all cameras. Latest graphics drivers installed (using Intel UHD630 on-board graphics).
Brand new PC build, no issues with any other hardware/software.
Any help appreciated, it's driving me mad!

In Develop:
