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:

Hi Rikk, would you please look at this problem? Camera; Insta 360 one X2, file is DNG two fisheye lens picture. they have to be processed in Insta 360 Desktop app, export is 1 jpg file and 1 DNG flat rectangular 360 file. The jpg is ok but not very nice processed and the DNG file will not open in ACR in PS or Bridge. In Lightroom it opens but you first won't see a preview after; develop, exposure ± it will show and workes ok... but I need to open them in bridge can you please help me with this bug? Insta 360 will not help me!
