p5.js version

2.3.1 to 2.3.3

Web browser and version

Chrome 154.0.8037.58 Same is happening in Safari - this isn't a browser issue.

Operating system

mac OS 26.7 and windows 10

Steps to reproduce this

Steps:

Randomly draw a lot of points. The points will band into sections on the x-axis . The sections are marked at 128, 256, 512, etc, with fewer points being drawn the higher the section.
This only happens in p5 versions after 2.3.0

Snippet:

function draw() {
for (let i = 0; i < 10000; i++) {
point(random(width), random(height));
}
}
