Steps to reproduce this

Steps:

  1. Draw ellipse(400, 400, 400,400);

  2. Change the y-coordinate to 440

  3. Error

  4. Draw ellipse(400, 0, 400,400);

  5. Change the y-coordinate to -1

  6. Error

I was not able to repro with changes to the x-coordinate
I was able to repro with line() and rect().
Errors go away with pre 1.8 versions.

Error:
TypeError: Cannot read properties of undefined (reading '9')

🌸 p5.js says:
