Bug description

Stroke is shaking when rotates. Only stroke does that, not the filled shape itself.

void draw(){
noFill();
stroke(0, 150, 255); // Blue color
strokeWeight(4);
rotate(radians(angle));
arc(0, 0, 150, 150, 0, PI + HALF_PI);
}

Steps to reproduce this

1. set frameRate to 60

2. run code:

void draw(){
noFill();
stroke(0, 150, 255); // Blue color
strokeWeight(4);
rotate(radians(angle));
arc(x, y, 150, 150, 0, PI + HALF_PI);
}

OR

void draw(){
noFill();
stroke(0, 150, 255); // Blue color
strokeWeight(4);
//rotate(radians(angle));
arc(x, y, 150, 150, radians(angle), PI + HALF_PI + radians(angle));
}

3. observe shaking of the rotating arc

snippet

float angle = 0;

void setup() {
  size(400, 200);
  frameRate(60);
}

void draw() {
  background(30); 
  
  pushMatrix();
  translate(width/2, height/2); 
  
  noFill();
  stroke(0, 150, 255); 
  strokeWeight(4);
  rotate(radians(angle));
  arc(0, 0, 150, 150, 0, PI + HALF_PI);
  
  popMatrix();
  
  angle += 5;
}

Would you like to work on the issue?

No, I’m just reporting the issue

Inizia eseguendo gli snippet setup() e draw() forniti in Processing 4.5.2 su Windows con frameRate 60, quindi confronta l’arco rotante con e senza rotate(). Riproduci il tremolio del tratto mentre la forma riempita rimane stabile. Il lavoro è completo quando l’arco rotante viene renderizzato senza tremolii visibili del tratto negli esempi forniti.
