Problems processing 16 tiff image from Deep Sky Stacker.

[geekdave]

I'm a relatively new affinity user. I'm using it to process tiff files from Deep Sky Stacker.

Yes, I know that affinity photo has its own astrophotography workflow - I dont trust it yet. I cant trust it to edit tiff files from deep sky stacker yet.

Here's the story: When I do my initial stretch of the image, these weird rectangles appear in the image. I thought these were artifacts from deep sky stacker but I can watch them get added to the image after the stretch process, and once I see them in the image, if I ctrl-z, they go away.

I am using a laptop with 8GB of ram, and in tel graphics card. For grins, I turned off opencl, and switched to WARP (whatever that is), and things really went to hell.

What kinds of troubleshooting information do I need to provide to you so that I can get help with this problem - because my images are basically useless after I do my post processing...

Hi, and welcome to the forums, @geekdave

Please try with deactivated hardware acceleration. To do so, go to Edit -> Preferences -> Performance.

Make sure that the drivers, especially those for the GPU, and Windows are up to date. WARP uses the CPU for rendering and is the slowest variant.

This is a very strange problem.

I finally managed to get an image produced with none of the artifacts in it. But I didn't have to update drivers, or change an affinity photo performance settings.

I dont know  what caused this problem, but if it happens again, I'll open another issue.

Thanks.
