I will just copy the contents of my issue from the facebook post I had made. Meant to post this here a lot earlier, but life got in the way:
I’m not sure if it's by design, or a bug, but basically: When I draw circles in the pixel persona, I’d expect them to be as round as I draw them. However, for the lack of a better term, they look a bit ‘low poly’. Lots of edges instead of organic curves. Did anyone also encounter this, or maybe know what causes this?
I’m using a Huion GT-191, Windows Ink enabled, on Windows 10. Had no performance issues whatsoever with my other raster-based art apps (Krita, Clip Studio Pro, etc.)
Attached a screenshot, please zoom in to spot the harsh edges.
If it's of any relevance, I use a dual-screen setup and they're both set at 1920x1080. I only have Affinity Designer open on one screen. Also encountered this issue with the Affinity Photo trial (I bought Designer by now and love it! Apart from this problem.)
