Jeroen Posted July 10, 2019 Share Posted July 10, 2019 In attached project, the following shows artifacts appearing when applying a live denoise filter, even after resetting the filter: With the denoise filter deactivated the artifacts disappear: Exporting to jpg of the project with the filter active also shows artifacts, although different ones: Exporting with the filter deactivated gives a clean picture. The project can be closed and reopened, and the behaviour remains. Jeroen. IMG_2333_Golf.afphoto Quote Link to comment Share on other sites More sharing options...
Staff Chris B Posted July 11, 2019 Staff Share Posted July 11, 2019 Hey Jeroen, Unfortunately the file you attached is corrupt for me. Perhaps attaching such a big file to the forum caused this... I cannot reproduce it on my own file which I have set up like yours in the screenshot. Does disabling Metal compute fix it? (Preferences > Performance.) You can try uploading the file again to this Dropbox folder if you'd like.

There are a few instances where we have had to suggest disabling Metal compute for now. This does not mean that there is necessarily anything wrong, your system just works better without it. In the update to 1.7 I believe we switched it on by default.

Yet, I may misunderstand you here... but it seems to me there is definitely something wrong at the moment. I have a 2019 Mac with all software up to date. You are certainly not suggesting that Metal support is fine as it is, and thus needs no fixing? Then, why is it not working as expected?

Staff Chris B Posted July 11, 2019 Staff Share Posted July 11, 2019 Hey Jeroen, I meant nothing wrong with your system. Once we have the file from the Dropbox link I provided we can look into why the glitch is happening with this file. Turning off Metal compute in the meantime will be your workaround until we can figure out why this is happening. Please provide a screenshot of your 'About this Mac' screen so we can get the specs.

Staff Chris B Posted July 11, 2019 Staff Share Posted July 11, 2019 Well I'm seeing the glitch in your file so we can pass this to the developers. Quote How to format a bug report | Learning Resources | List of V2 FAQs | YouTube Tutorials Link to comment Share on other sites More sharing options...

Staff Justin Posted July 23, 2019 Staff Share Posted July 23, 2019 Hi Jeroen There are a few isolated pixels in your file that have red channel values of NaN (not a number). The live denoise filter is getting confused by these and producing black squares centred on the corrupt pixels. I'm guessing the image comes from a RAW file via the Develop persona. Do you remember what adjustments you applied in Develop? Thanks Justin Quote Link to comment Share on other sites More sharing options...

Do you remember what adjustments you applied in Develop? Thanks Justin Hi Justin, Interesting.I can see that NaN values might certainly cause erratic behaviour. The question of course is where they come from. You are correct in that I developed from a raw file, and I did it in AP. I do not keep records of develop adjustments. Normally I tend to keep development settings simple and leave most of the work to the Photo persona, but I do not remember exactly what I did here. I can provide the raw file though, if that might be of use. It is a Canon .CR2 file. Let me know if you would like me to. Best regards, Jeroen.
