Done. Thx A.

Edited the gaussian Blur from 0 to 9: - From 0 pixel to 0,9 pixel no Nans - From 1 Pixel up NaNs are always there Did try with motion filter. I am at the very beginning of affinity learning curve (as well as of any similar software) so I do not exactly how motion blur works. Any way: when I apply motion blur layer, NaNs appear also in affinity and they remain, even if differently, in Jpeg exported version.

I did some testing, to help in finding the issue. I exported one Jpeg for each layer that I added in my work flow; In total I added 5 layers on top of the background (Pixel layer) To explain: I exported a Jpeg with only pixel layer, then a jpeg with pixel layer and first layer added, than pixel layer and two layers, and so on Artifacts appears when adding the gaussian blur level, no artifact until the second layer.

Thank you for pointing it out. Both are running on Macs with exactly the same configuration, same age, CPU, RAM and Graphic Card. May be is there something related to this configuration and the layers we both have been using?

Hello, I am running Affinity on a MacBook Pro mid 2015, IOS 10.15.1, exporting Jpeg Best Quality. Same problems happens exporting to Tiff 16 bit, Tiff 8 bit and Jpeg medium quality. Colored squares do not appear exporting to PDF file. Hope this might be useful A.

Hello, did you check the photos? Have you any answer/solution? Thx A.

Hello, thank you very much. I uploaded the photos to the posted link. A.

Hello, I have a problem working with a photo. I developed it from RAW, created different layers mainly for Brightness & blurring. When I see it in affinity it is ok, when I export to Jpeg colored squares appears in the photo. NEF Raw from D850, Tried to upload jpeg but failed, can mail jpeg and AFF file if necessary . Anyone can help? Thx
