altae Posted December 5, 2020 Share Posted December 5, 2020 I wanted to use the High Pass Live Filter to apply High Pass Sharpening to a photograph. Unfortunately there seems to be something wrong with this Live Filter as it introduces distortions when merged to a new layer or when exported. The attached screenshots as well as an exported image should clarify what I mean. There are no distortions introduced with the standard High Pass Filter.

altae Posted December 9, 2020 Author Share Posted December 9, 2020 Looks like it has something to do with OpenCL hardware acceleration. As soon as I disable it the distortions are gone (when merging layers as well as when exporting). And it seems I'm not the only one who has been experiencing such issues with OpenCL: https://forum.affinity.serif.com/index.php?/topic/129141-random-squares-at-export/ Btw I changed the title as the issue is still present in the latest beta.
