[Affinity Photo 2.5.6] Inpainting is excruciatingly slow.

[OhItsStefan]

Generating a small fill area on a medium-sized canvas takes well over 5–10 minutes, when before it rarely took more than 10 seconds.

I've tried isolating the part I am trying to fill, that way no other resources are being used for the rest of the document. I've tried putting it in a new document, but no results.

It would help if you share the file causing the issues, adding screenshots of your performance settings, and screen recordings of good / bad performance.

10 seconds is excessive, so curious to learn what you do. Normally inpainting never takes more than a few seconds, but it really depends on the actual image and context.
