Heap allocation growth

Created by: sj-unit72

Description

A simple Processing 4 app seems to add between roughly .5MB to 1MB of memory usage every 5 seconds.

Expected Behavior

If the app isn't doing anything, it shouldn't be adding memory, right?

Current Behavior

Adding .5mb to 1mb of memory usage every 5 seconds. In the time searching for similar issues and typing this message, the app went from 150MB to 295MB

Steps to Reproduce

Create a new app, draw 2 squares, and run it. Now check memory usage of the app.
App used:

void settings(){
    size(1920,1080);
}
void draw(){
     //Fill background
    fill(0);
	  noStroke();
	  rect(0,0,1920,540);

    //Key background
    fill(128);
	  noStroke();
	  rect(0,540,1920,540);
}

Your Environment

• Processing version: Processing 4.1.2 for Apple Silicon
• Operating System and OS version: Monterey 12.6.2

Start by reproducing the reported Processing 4.1.2 sketch on Apple Silicon with Monterey and monitor the application's memory over time. Since the issue names no source file or test, trace the idle draw loop and allocation behavior before identifying the cause. Done means the minimal sketch no longer shows unexplained memory growth while idle, with a regression test or reproducible verification.
