pixel artifacts when merging layers or exporting file to jpeg

[Alexander Alasdair]

I recently bought a new notebook, since the integrated graphics card of my old one was quite weak for Affinity Photo.
(New Notebook: Lenovo IdeaPad 5 Pro 16ARH7, RTX 3050 Ti, AMD Ryzen 7 6800HS Creator Edition)
After applying a few adjustment-layers followed by either merging visible layers or directly exporting the file as JPG, there will be a bunch of artifacts introduced.



"Hardware-accelerated GPU scheduling" is turned off on Windows, as mentioned in this article.



Same issue occurs on Windows 10 and 11, tested it on two different SSDs.
The problem occurs not only on this very image, but when applying several adjustment-layers in general.
So far, I couldn't narrow it down to one specific adjustment-layer.
I never had such issues on the old device.
Windows is up-to-date, notebook-drivers are up-to-date and graphics-drivers for the dedicated Nvidia as well as integrated Radeon card are updated as well.
I also made sure that Affinity Photo only runs on the dedicated card for better performance.



Affinity Photo Version: 1.10.5.1342 (Downloaded via Windows Store).

If I missed any details, feel free to ask.
Any tips and hints are highly appreciated! Thank you!

Welcome to the Serif Affinity forums.

As an experiment, you might try opening Preferences on Affinity Photo, and at the bottom of the Performance section turn off Hardware Acceleration (OpenCL). Then, after you restart Photo, see if you still have the problem.

I would also check that you are running the latest version of the Nvidia drivers.

Yes indeed, I confused Windows HW-Acceleration with Affinitys own HW-Acceleration settings.

Disabling as follows removes the pixel artifacts. Problem solved!

Edit > Preferences > Performance > Hardware Acceleration: [_] Enable OpenCL compute acceleration.

Thank you very much!
