titan3025 Posted May 27, 2022 Share Posted May 27, 2022 Hi all, I am running Affinity Photo 1.10.5 on an AMD 3800X with a nVidia 2060 SUPER (studio driver 512.96) graphics card. When I do a batch processing to convert images with parallel processing and hardware acceleration enabled I see image corruption in the results. This in the form of artifacts (little rectangles). As soon as I turn off parallel processing this effect stops and the converted images are clean and as expected. If I turn off hardware acceleration the parallel processing also produces results without corruption. I wanted to attach two example photos but I seem not to be able to attach files to posts. Is this known and are you working on this? Cheers Titan3025 Quote Link to comment Share on other sites More sharing options...
PeteMacca Posted May 27, 2022 Share Posted May 27, 2022 Yes..., it's known. Hardware Acceleration (for some users) can causes artefacts to corrupt the image. Are they working on it? I sure hope so! titan3025 1 Quote Link to comment Share on other sites More sharing options...

Are they working on it? I sure hope so! This is an interesting one, though, as it seems like an interaction between parallel processing and hardware acceleration. titan3025 1 Quote -- Walt Designer, Photo, and Publisher V1 and V2 at latest retail and beta releases PC: Desktop: Windows 11 Pro, version 23H2, 64GB memory, AMD Ryzen 9 5900 12-Core @ 3.00 GHz, NVIDIA GeForce RTX 3090 Laptop: Windows 11 Pro, version 23H2, 32GB memory, Intel Core i7-10750H @ 2.60GHz, Intel UHD Graphics Comet Lake GT2 and NVIDIA GeForce RTX 3070 Laptop GPU. iPad: iPad Pro M1, 12.9": iPadOS 17.4.1, Apple Pencil 2, Magic Keyboard Mac: 2023 M2 MacBook Air 15", 16GB memory, macOS Sonoma 14.4.1 Link to comment Share on other sites More sharing options...
Staff Dan C Posted May 27, 2022 Staff Share Posted May 27, 2022 Hi @titan3025, Welcome to the Affinity Forums Many thanks for your report and I'm sorry to hear you're having trouble. I can confirm this issue is already logged with our developers, specifically relating to Hardware Acceleration and Parallel Processing with in a new Batch job - we've previously made changes to the codebase to try and improve this and this is the first documented report of the issue since these changes were made - therefore I'll be informing our developers that this can still occur and provide them with the system details you helpfully have provided already. I hope this helps! titan3025 1 Quote Please note - I am currently out of the office for a short while whilst recovering from surgery (nothing serious!), therefore will not be available on the Forums during this time. Should you require a response from the team in a thread I have previously replied in - please Create a New Thread and our team will be sure to reply as soon as possible. Many thanks!

titan3025 Posted May 27, 2022 Author Share Posted May 27, 2022 Hi Dan, Thanks for the update and informing the developers that this can still occur. Let me know if there is anything else I can provide you with so the developers can address this. Dan C 1 Quote Link to comment Share on other sites More sharing options...
Gregory St. Laurent Posted June 3, 2022 Share Posted June 3, 2022 I also can confirm. Turning off parallel processing clears up the issue for me, so try doing this as a work around until a fix is issued.

southerner Posted June 14, 2022 Share Posted June 14, 2022 I can also confirm. In my situation it is simply when exporting to jpg after doing some editing. I have recently upgraded camera (Panasonic S5) and almost all my camera produced jpgs (at "fine" quality) are now producing these artifiacts after editing. Editing is usually only a little saturation plus brightness & contrast. Incredibly frustrating until I researched and found this forum topic. It would also happen on my old Panasonic G85 but only occasionally when doing complex editing. I've just turned off hardware acceleration and problem seems to have gone away. Up to now I have had to use Merge Visible multiple times across the various adjustment layers to produce two images, both with artifacts but in different places. Then I copy clean cutouts from one of these images to the other so as to get one clean image. Then export just that clean layer. Completely messy and frustrating so this "solution" is much appreciated, thanks. However it would be nice to have the problem fixed Quote Link to comment Share on other sites More sharing options...
Staff Dan C Posted June 14, 2022 Staff Share Posted June 14, 2022 Hi @southerner, Welcome to the Affinity Forums Sorry to hear you're experiencing the same issue and many thanks for your report. So that I can log this further with our developers, can you please confirm your system specs for me, specifically the CPU & GPU in use? Many thanks in advance!

southerner Posted June 14, 2022 Share Posted June 14, 2022 Cheers @Dan C, my specs are: Processor/RAM: Intel Core i7-6700 CPU @ 3.40GHz / 16Gb Motherboard: Gigabyte GA-B150M-D3H Graphics: Intel HD Graphics 530 Display: Philips 273PLPH 27" Am suspecting that since I don't have a specific, high-spec graphics card installed, the hardware acceleration option is probably inappropriate for me anyway? Hope this helps. Dan C 1 Quote Link to comment Share on other sites More sharing options...
PeteMacca Posted June 15, 2022 Share Posted June 15, 2022 Intel HD or UHD graphics don't always play nice with Affinity Photo & Hardware Acceleration. I keep mine off. southerner 1 Quote Link to comment Share on other sites More sharing options...
