_fluffy Posted September 2 Share Posted September 2 When drawing with Affinity Photo, I often run into issues where the brush pressure causes what looks like quantization in the brush radius: There's a distinct lack of tapering and smoothing between the various steps on the brush size, which are all being rounded to the nearest pixel radius. I'm using a Wacom Intuos which hasn't had problems like this in other drawing software, and it particularly happens on the standard round brushes set with pressure-based size jitter: Is there a way to get smooth brush tapering (with subpixel sizes) like what most other drawing programs support?

walt.farrell Posted September 2 Share Posted September 2 Could we see a screenshot of the Performance section of your Photo Settings, please? Also, how zoomed-in are you in the screenshot you already gave us?

_fluffy Posted September 2 Author Share Posted September 2 Sure, here's the performance section: And I'm zoomed in pretty far, and those jumps are a single pixel at a time. But even zoomed out it's pretty bad-looking, and other drawing tools (such as Photoshop, Clip Studio Paint, heck even GIMP) don't have this issue since they support some amount of subpixel brush sizing. walt.farrell 1 Quote Link to comment Share on other sites More sharing options...
cgidesign Posted September 4 Share Posted September 4 Seems to be related to this post from 2022 ! There is no bug-number assigned to it. I guess, it is not something that will be optimized in the forseeable future. Quote Link to comment Share on other sites More sharing options...

When the Serif team gets to this topic, they may be able to confirm it's related, and give us a new bug number.

_fluffy Posted September 4 Author Share Posted September 4 Ah thanks, I'd done a search figuring others had experienced this too, and I didn't expect it to be that far back! Hopefully someone on the dev team takes a look at it now. It does seem like a workaround is to set the brush to 99% hardness, at least.

Staff MEB Posted September 5 Staff Share Posted September 5 This is indeed the same bug as pointed out by @cgidesign above. Bug report updated/bumped (now logged as AF-4217).
