Pen pressure issues when using hardware acceleration

[corjohnson]

I've been using Affinity Photo for painting & drawing, but when I have hardware acceleration turned on my pen pressure is occasionally ignored, and a "full pressure" dot kind gets placed instead of another light stroke.

I've attached an example of what it looks like. In this case I was using the preset brush: "Comics G Pen", and trying to do some warmup lines by rapidly doing light, low pressure strokes in the same direction.

I have this happen all the time when I'm actually trying to draw and it's really frustrating.

What Application are you using? [Designer/Photo/Publisher]

Photo

Are you using the latest release version?

Yes

Can you reproduce it?

Yes

Does it happen for a new document?

Yes

-----------------------------------------

OS: Windows 11

Tablet: Wacom Intuos Pro Medium

Hardware Acceleration: Yes (does not seem to happen when hardware acceleration is OFF)

Expected: My brush stroke would continue to be light and low pressure like the other 10-15 previous strokes

Actual: After a number of brush strokes, I will occasionally get a large/high pressure dot instead of my usual stroke

Repro Steps:

1. Open a new document
2. Select the Paint Brush Tool
3. In the brushes panel, select a brush with pressure dynamics for size and/or flow
   1. Comics G Pen is what I used in the example
4. Using faint/light pressure, draw lines in the same direction/motion light and fast
   1. The key here I think is moving in similar directions? I notice it when I try to shade with a bunch of small lines
   2. Might take 20-30 strokes to have it occur

So I was digging through the settings and didn't realize there was a tablet precision mode, it was set to low, which I'm guessing is the default.

Changing it to windows ink fixed the issue for me
