Hi,
I recently purchased Affinity Photo along with a Huion Display Tablet (Kamvas GT-156HDV2) and was trying out the brush tool when I noticed that the brushes don't taper very nicely, especially when I start the stroke (was drawing from bottom to top in the attached image). and it also ends a bit funky too.
Not sure if it's a tablet driver issue (also contacted Huion) or could be a compatibility problem?
UPDATE:
This also seems to be a problem in Affinity Design, but doesn't look to be as bad.
Also, even when I apply pressure at the beginning of the stroke, it starts off with the thin line before it jumps to the correct size.
I use other programs as well (Autodesk Sketchbook and Clip Studio) and I have not encountered this problem
