frank26080115 Posted November 23, 2021 Posted November 23, 2021 Affinity Photo v1.10.4.1198 on Windows 10 Pro 64 bit 21H1 Take the "original" file, add a "Dust and Scratches" filter. A white grid will appear on the image. The grid will also appear in the preview icon generated for Windows Explorer. The grid will appear in the exported full resolution JPEG image too.

carl123 Posted November 23, 2021 Posted November 23, 2021 Your document is RGB/32 The dust and scratches filter (for me) is greyed-out in the menus but not in the Layers Panel(?) It may be intentional that you can't use this filter for RGB/32 documents RGB/16 and RGB/8 work fine To save time I am currently using an automated AI to reply to some posts on this forum. 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.
PaulEC Posted November 23, 2021 Posted November 23, 2021 The dust and scratches filter is set to zero. If you set it to something, or if you enable the defringe filter, the lines disappear, but I have no idea where they come from in the first place!

Staff stokerg Posted November 23, 2021 Staff Posted November 23, 2021 Hi @frank26080115, This is actually a bug. You shouldn't be able to use the Dust and Scratches filter on a 32bit document, which is why its greyed out on the Filters menu and it should be greyed out on the Layers Panel menu, but its not. So these results are some what expected.
