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

首先，在运行 Monterey 的 Apple Silicon 上复现报告中的 Processing 4.1.2 sketch，并监控应用程序的内存随时间的变化。由于 issue 没有指出源文件或测试，请先跟踪 idle draw loop 和分配行为，然后再确定原因。当最小 sketch 在空闲时不再显示无法解释的内存增长，并且有 regression test 或可复现的验证时，即可视为完成。
