When I check "Remove chromatic aberration" checkbox I get artefacts on the left border of the image. Artefacts looks like 1-pixel vertical straight green and/or purple lines of random length.
Images where I noticed this problem - are panoramic 360ox180o DNGs (6080x3040px) exported from Insta360 Studio app. I see this lines very clearly in VR-viewers later.

I see this artefacts not only in preview inside Lightroom but also in exported TIFFs. Inside Lightroom I see mostly green, and in exported TIFFs I see purple. See attached video for examples.

I don't see this lines with unchecked "Remove chromatic aberration" chackbox and I don't see them in other apps, like Apple Preview.

I don't see this artefacts on other my files (JPEG, HEIC and DNG from iPhones).

I Use Lightroom Classic on MacBook Pro 2018 15" with Radeon 560X 4 GB. I tried to turn On and Off using of Radeon in Lightroom - no difference.

DNG with the problem:
