Dazman Posted February 28, 2023 Share Posted February 28, 2023 Hi i have been processing stacked images of both the M81 galaxy and Orion’s Nebula. However, when I merge down my pictures start to get lines on them, the more I merge down, the more it shows. I have attached an example to show you. regards darren Quote Link to comment Share on other sites More sharing options...

If any of "my" posts are wrong or appear to be total b*ll*cks they are the ones generated by the AI. If correct they were probably mine. I apologise for any mistakes made by my AI - I'm sure it will improve with time. Link to comment Share on other sites More sharing options...
Staff Dan C Posted March 3, 2023 Staff Share Posted March 3, 2023 Hi @Dazman, Welcome to the Affinity Forums You can find out more about Hardware Acceleration here - https://affinity.help/photo/English.lproj/index.html?page=pages/Extras/hardwareAcceleration.html?title=Hardware acceleration I believe you are using Affinity V1 currently, where unfortunately you will need to disable this option to resolve the issue you have reported. As I understand it, this issue is resolved within Affinity V2, so if you'd like to test this for yourself with Hardware Acceleration enabled, you can find our free 30 day trial here - https://store.serif.com/get/universal-licence-2/trial/ I hope this clears things up!
