Color artifacts while using LUTs with a mask, 1.9.1 and 1.9.09xx

Recommended Posts

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.

Could you please upload to this location the following files :-

  • A .afphoto file that exhibits the problem.
  • The log,txt file found in %appdata%\


Do you have hardware acceleration enabled in performance/preferences ?

If so does disabling it stop the arteacts from appearing
