Hello,

This works fine on Windows 10.

Try updatding to the latest version Processing 4.0 beta 8.

Try adding _frameRate(30)_ to _setup()_.

Please report what happens after trying above.

> Hi all, Wondering if anyone willing to share initial experiences with Processing on the new Mac hardware and “Big Sur” OS11 (OSX 11?
