Steps to reproduce this

Steps:

1. Create a speed test using WEBGL, for example here I created random triangles moving around: https://editor.p5js.org/shangtsung/sketches/qMZ_4M4c6
2. You can see that the shapes move around really slow, the whole browser window becomes very slow. Until I remove the 'WEBGL' from createCanvas(800, 600, WEBGL), then everything moves very fast.
3. Also everything moves very fast (including when WEBGL is included) in older p5.js versions before 1.0.0.

So something was messed up in p5.js since version 1.0.0 (including the latest version) that made it very slow.

Or am I missing something?

Probably I was missing this library?

It seems to make this too complicated. Should I switch back to the very old but fast p5.js version or how exactly should I edit my code to make it fast using the latest p5.js?

Start by running the linked p5.js WebGL sketch and comparing its performance with versions before and after 1.0.0, focusing on the createCanvas(800, 600, WEBGL) entry point. A useful result would reproduce the slowdown, identify the regression in the rendering path, and verify comparable movement speed in the latest version.
