P: X-T2 Fuji Files have small purple artifact at edge of image after Denoise

@kernpanik Do you use RAF or DNG raw files?

@johnrellis Thanks a lot for your test of my reported problem.

@kernpanik is your X-T2 problem gone?

Yes, it's fixed for me. 

"It was fixed in 15.3.1 in Camera Raw ..."

Yes but it was fixed only for the X-H1 camera model but this is only one out of n models which often have different X-Trans Sensors. In the source thread there are several users which reported the same bug but on different cameras with different sensors (I already mentioned 3 of them). I guess that Adobe AI denoise needs a fix for each of the X-Trans sensors. By the way my camera model X-T2 is also there and as you now know the problem is not fixed.

I will try to get some light into the shade and asking therefore the prevoius discussion attendees:

@kernpanik is your X-T2 problem gone and happened it with RAF raw source files?

@saintleger is your X-Pro 2 problem gone and happened it with RAF raw source files?

@Debruineogenboy is your X100F problem gone and happened it with RAF raw source files?

@SoylentYellow is your X100F problem gone and happened it with RAF raw source files?

@Ory217759190xsq is your X-T20 problem gone and happened it with RAF raw source files?

@martat14582229 is your X-Pro 3 problem gone and happened it with RAF raw source files?

If all of them are happy now it would mean that not the X-Trans sensor is the culprit but may be my *.raf to *.dng conversion at photo import to LrC. Hopefully at least some will answer my question...

"I have not read the entire source thread."

Please read the entire source post. It was fixed in 15.3.1 in Camera Raw and in 6.4 and 12.4 in Lightroom Desktop and Classic respectively. 

The fix was confirmed on 5.19 by an afflicted customer. 

If you find that other cameras are affected, the title can be changed. 

From my previous post: 

"I expect that all Fujifilm X-Trans RAW files are problematic for the AI denoise, i.e. not only X-H1 and X-T2. (I will try to proof this if I have time in the next days.)"

This is already proofed in the source post! There are the following camera models mentioned X-Pro 2, X-PRO 3, X100F and may be some more. I have not read the entire source thread.

The failure is in the Camera Raw engine and fails across all clients ACR/LrD and LrC. It belongs in Camera Raw as they have to fix it for all the clients.

@Rikk Flohr: Photography  1) Why is my post now at "Camera Raw" instead of  "Lightroom Classic"? The AI denoise tool is a part of LrC, isn't it?

2) You have changed my title "AI Noise reduction for Fujifilm DNG files produces purple lines also in LrC 12.4 (June 2023)" which was aligned with the title of the source post P: AI Noise reduction for Fuji X-H1 files produces purple lines on edges . Your new title hides the relation and implies that it is only an X-T2 bug. I expect that all Fujifilm X-Trans RAW files are problematic for the AI denoise, i.e. not only X-H1 and X-T2. (I will try to proof this if I have time in the next days.)

@Rikk Flohr: Photography, please consider moving to Bugs. Using the sample file provided, I see the same purple borders on the enhanced DNG (LR 12.4 / Mac OS 13.4):
