phil_k Posted February 4, 2021 Share Posted February 4, 2021 I have tried exporting 25 photos to jpeg noticing that sometimes you get multiple colored, white, or black squares on the export. It appears random. As you export the same file multiple times the squares move as well as their color changes and the number of them. Every export is hit or miss. You can see the colored squares on the export preview window as well. Sometimes it takes up to 10 attempts at export before you get a clean (no squares) and sometimes on the first attempt. More than often you get a clean export. It appears related to OpenCl since if you turn it off then it appears to export fine. I have a Ryzen 3700X, AMD Radeon 5500XT graphics card with the latest recommended driver. Chris B 1 Quote Link to comment Share on other sites More sharing options...
Tom99 Posted February 5, 2021 Share Posted February 5, 2021 I have the same problem with my Affinity Photo 1.9.0.932 Appears when using "Hardware Acceleration" combined with a live filter. In my case the problem disappeared when turning hardware acceleration Off. Same artifacts appears when using "Merge Visible" See Related Post: Square Artifacts Chris B 1 Quote Link to comment Share on other sites More sharing options...
Staff Chris B Posted February 5, 2021 Staff Share Posted February 5, 2021 Hi phil_k and Tom99, There are a few rendering issues with OpenCL and as you have both discovered, turning off OpenCL is the temporary solution for now. I will update the developers. Thank you very much.

phil_k Posted February 5, 2021 Author Share Posted February 5, 2021 Multiple users have a similar problem but I don't believe it is related to the files in use. I have had the same files export to jpeg with and without the square artifacts. Most of the time it works great, but every once in a while the squares appear during export and remain a problem for a while then it works for a while. Not sure if others have the same experience. Also, I have noticed that if I use the jpeg best quality preset I not sure if I have seen the issue. Quote Link to comment Share on other sites More sharing options...
