Brush shape flipping

[RedBeard]

When making an arched brush stroke the brush flips when approaching the horizontal orientation. This happens in all brushes I have tested where their rotation is linked to Apple Pencil angle. I show the same strokes performed in Procreate with a similar brush to demonstrate that this is not a flaw in the iPads pencil processing. 
I used the “Fluid Chisel Tip” brush with its default settings. 

Edit: this was on an iPad Air 4 running iOS 16 

This bug was also present in Photo v1

I'm not seeing that here. My Apple Pencil is version 1 though.

@RedBeard I can replicate it and fix it, not sure point of comparing to another design package that does not use same brushes though.

Turning off the rotation dynamics removes core characteristics of the brush (Sort of like fixing a flat tire by just removing the wheel). A brush that has its shape tied to pencil angle is critical to hand lettering for example. 

I showed another app with a brush who’s shape rotation is linked to pencil angle because in the past I was told this was a flaw in how Apple Pencil data is processed by the iPad. That doesn’t seem to be the case.

Ok, but Affinity brushes seem to have so much programability, there are many other options under rotation that also do not make these strange marks, how other softwares have their set must be difficult to compare, they could be using direction cyclic etc etc 

Isn't the point that you alter the brushes to suit your needs and there are several ways without disabling rotation to change it. (I was going to say fix it but the more I look the more I think it is by design given the flexibility of setup)

@Paul Mudditt

Unless there is a way to keep the brush rotation tied to the pencil angle without causing this defect in the stroke this is still a bug. Many other programs allow you to do this without such a stroke defect.

Hi @RedBeard

I have passed this over to our devs for further investigation.
