I am working on a photo passepartout, with a picture in the middle and a logo with font underneath, in Affinity Photo. Somehow, no matter what I do, the font always appears pixelated in the document, and in the exported file, even when I convert it to curves. It is shown sharply in Affinity Designer, but if exported from there it's the same problem. I have to say I'm quite new to Affinity and this kind of work, so I don't really know what I'm doing and what could be wrong, but web searches haven't helped so far. I attached a few photos to illustrate the problem.
The document is set at 300 DPI / 2250x2250px.
Let me know if there's anything else you need to know in order to help.
