Curve width is drawn with "overshoot" when used other than default pressure graph

[hunter_sk]

Problem description: Curve end is drawn with an "overshoot", when pressure is set to some non default values. 

Application: Designer 2.5.2
Platform: Windows 10
Reproducable: Yes, from new document
HW Acceleration: OFF, (ON = not supported)

Reproduce steps:

1. Create an V shaped line as on followed picture. More sharp the V shape is, more noticable the overshoot is.
2. Set curve Miter to some higher value, like 20 or so.
3. Edit curve pressure. Any slight change will do.

I can reproduce the issue on Windows 11. HW Acceleration on.

And something weird happened when the mitre value and angle are changed. It's not just an redraw issue, the expanded stroke proved that.

@KarlLegion Same here, even with the default Miter = 1.5. 

I'm attaching the file so this can be investigated → ADe_pressure_affects_round-cap_geometry.afdesign

Screenshot 1↓ - initial state

Screenshot 2↓ - slightly changed pressure destroys the geometry of the round cap

Screenshot 3↓ – modification of the curve / even greater deterioration of the geometry of the round cap

I have tested this in the new 2.5.3 update and I am not able to replicate this issue with this version.

Unfortunately also in version 2.5.3 is this problem still replicable on my machine. By the way, the step 3 is important. Can you post a video? Just curious how this could be that different on other system.

Still happens here on Mac OS with 2.5.3

@DWright I can't belive that you can't reproduce it. See the video below (ADe v2.5.3). 

The pressure algorithm is weak. What's even weaker is that the Stroke Width tool uses this weak algorithm.👎
