Lightroom/Camera Raw: Enhance Details causes cut out colored squares

Now tested on my 2012 Mac Mini at home. Still corrupts the resulting DNG. On the Mac Mini, I get an overall black image, with a few random squares of detail scattered about. The image fragment within the squares sometimes look okay, other times there are artifacts. Happens with or without "Use Graphics Processor" and on both uncompressed and losslessly compressed raw files from my Fuji X-Pro2 and X100F. Older raws shot with older firmware on the camera, brand new files shot today; doesn't seem to matter. I am thinking it is X-Trans combined with old and/or marginal graphics hardware. I also have a 2012 MacBook Air, but I am guessing I'll have the same results with it. All my computers are a number of years old and have low-end graphics hardware. Gaming and video editing were never anything I did either, so the lesser graphics hardware hasn't been an issue in the past.

Honestly, even if the enhance details didn't glitch, it is so incredibly slow to process on my old hardware that I probably wouldn't want to use it anyway, expect maybe for the occasional image I want to print really large. The differences I saw on the D750 files were extremely subtle, but of course if the X-Trans conversions were working, I might see a greater improvement there? Using PhotoNinja often gives me noticeable improvements, with fine detail and textures often looking more natural, without much of a speed hit even on my old computer, and integrates quite well with Lightroom too, so this new Adobe feature seems to be of dubious value for me personally at the moment.

I am guessing Adobe did not test this new feature on all that many older systems, like all the systems I am using, and I cannot really say I blame them either. Here is the info for the Mac Mini...

The preview is magnified. Use the zoom tool (bottom right in preview window)  to scroll to different parts of the photo. You would need to click the Enhance button to render the DNG to compare side by side.

The new Lightroom Enhance feature is creating these wonderfully, colorful gridded images. I suspect this is an issue with my GPU. I have a Mid 2010 Mac Pro with an upgraded NVIDIA GeForce GTX 680 4096 MB graphics card. This happens with every Fuji raw image I process. I successfully processed one iPhone Lr dng image with enhance, although I couldn't see any detail improvements in it.

I have the same problem, see the thread here. Interestingly, it's only X-trans files that exhibit the errors, Canon 1D X files render fine...
Mac OS 10.13.6, Mac Pro upgraded with Nvidia GeForce GTX 1080, latest Nvidia Web Driver and latest CUDA framework. Can't test on 10.14 since Nvidia does not have drivers for it.

I have the "black square" problems also.  I converted a RAF from my X-T3 to a DNG.  Still had black squares but significantly fewer.  I ran Enhance Details on the cactus image from Andrew and that had no problems.  Using LR 8.2 on a MacBook Pro running High Sierra. 

So this is interesting: the enhanced DNG files that appear scrambled in Lightroom open just fine in Capture One!

I would like to know if this problem can be fixed by Adobe. I have read the article in GPU requirements for Lightroom. My video card addresses the open cl spec but is older. If I update, my GPU will this feature work?

My Mac mini 2014 seems to have the necessary specs; however I do get black rectangles, and it takes aboitn4 minutes to develop. Therefore not useful to me unfortunately

This problem was SOLVED for me by upgrading to Mojave (from High Sierra). Definitely worth it for me as I'm seeing  a massive improvement in the details from my Fuji X-T2! 

This reply was created from a merged topic originally titled Lightroom Classic CC: Line artifacts in Enhance Details (merging).

That’s subtle by comparison of what I’m getting. Enhanced details takes about 10 minutes to process one photo and this is what I get as a result. I’m running the most current version of Mac (10.13.6) This update is a far cry from what Fuji shooters were expecting when we read it improves Fuji x-trans files and absolutely not what we should have to deal with. Really considering leaving for pretty much anything else. I’m getting tired of Adobe sitting in the corner eating glue while everyone else has figured out how to read and display Fuji RAF files flawlessly for years now

Note: This conversation was created from a reply on: Lightroom Classic CC: Line artifacts in Enhance Details.

I have almost exactly the same issue - about half of the picture is fine (and enhanced), half of the squares are black. Enabling/disabling GPU acceleration does not do anything (HD6970M acceleration is not supported by Lightroom anyways).

I can confirm that it worked for me after upgrading to Mac OS 10.14 (Mojave), appareantly bringing some updates and improvements to the Apple machine learning framework necessary for this (as I understood it, correct me if I'm wrong).

BUT! Be aware that Apple cut it's support for a wide range of NVidia graphics card with the Mojave update. Although officially being 'unsupported' it has been possible before to use NVidia GPUs (e.g. in an upgraded Mac Pro 4,1 or 5,1), but after the Mojave update Apple seems to refuse to cooperate with NVidia to develop / update new drivers required, rendering NVidia cards useless. There is all sorts of complaints about this on the internet and it seems that this will be a permanent issue.

I was running a Mac flashed NVidia GTX 980 in my Mac Pro 5,1 and switched to a Sapphire RX 580 PULSE for around 200 €, which is fully supported by Apple. Everything works nicely again and performance is even a bit better but I still would have appreciated to spend the money on something else... ;)

For those experiencing the color tiling issue in Enhanced Details who are using Nvidia RTX series cards, a new driver has been released.The driver version that has the fix is called 419.67 (this is the term that Nvidia uses on their web site).  It was just released yesterday, 3/25.  Please update your driver from the Nvidia site and let us know if you continue to have the issue afterwards.
