Hi @Chriz96,

You can use your original code with only the FX2D renderer:

```processing
// Original:
// https://discourse.processing.org/t/aliasing-issue-processing-4/47785

import processing.javafx.*; // Added import. You must download library to use.

float a = 0;

void setup() {
  size(400, 400, FX2D); // Added FX2D
  rectMode(CENTER);
}

void draw() {
  background(255);
  translate(width/2, height/2);
  rotate(a);
  rect(0, 0, 200, 200);
  a += 0.02;
}

void mousePressed() {
  saveFrame("any3.png");
}

```
