Zeel Posted February 26, 2021 Share Posted February 26, 2021 After a while Affinity photo starts showing some color artifacts when I use several LUTs that a grouped and mask applied. Artifacts appear where mask transitions from white to black, in midtone area, and happens only after I work with a file for a while. Restarting Affinity Photo helps for some period of time. Seems like it also affected by having other files open - more likely to happen. Quote Link to comment Share on other sites More sharing options...

If so does disabling it stop the arteacts from appearing Quote Link to comment Share on other sites More sharing options...

Zeel Posted February 27, 2021 Author Share Posted February 27, 2021 I finished a similar edit (not the same file though) with OpenCL off and it didn't exhibit the artifacts. Quote Link to comment Share on other sites More sharing options...
