I just updated to the new 12.3 version of LRC and tested it out with a couple of files from my Fuji X-H1 for both images the resulting DNG-file has purple lines going across the top and right sides of the image.
Version of the app: LRC 12.3
Platform and OS version: Windows 10 Pro
Basic steps to reproduce the problem: Run AI Denoise at 50% on a Fuji X-H1 file
Expected result and actual result: Clean image / purple lines on top and right sides of the image
I'll attach a few screen captures to showcase the issue.
