Canvas background problem!

ignas

hi there, I have a problem with p5.js canvas background color.I created a clock and I want to change black canvas color to transparent. Looks nothing special, but after I changing it, arrows leaving the mark after every second, minute after every minute ... (have a look at image here https://ibb.co/dNqYT6 )

how would you fix it? function setup(){ createCanvas(180, 180); angleMode(DEGREES); } function draw(){ background(0, 128, 0, 0); translate(90,90); rotate(-90);

Have you tried calling clear()? I didn't see it in your code inside draw(). :-@
