Description

i was playing with svg jerking on screen and to verify P2D or P3D performances i found strange behavior.
The svg shape shift to right. it is supposed to center it, and it is with no renderer added.

Expected Behavior

the svg should be in the same place

Current Behavior

when a renderer is added, the svg shift to the right.

Steps to Reproduce

PShape motif;

void setup() {
  size(600,600);
// size(600,600,P2D);
  motif = loadShape("mot.svg");
  shapeMode(CENTER);
}

void draw() {
  background(200);
  shape(motif, width/2, height/2, width, height);
}
  1. add the renderer in size (uncomment the line)

Research direction

Start by running the provided sketch in Processing 4.3 with the default renderer and then with P2D or P3D, using the reported SVG shape and centered shapeMode. Compare the rendered position and trace the renderer-specific shape placement; done means the SVG remains in the same place across renderers.
