Blank sketch window on Mac

[villares]

Test script:

from p5 import *

def setup():
    size(640, 360)
    no_stroke()
    background(204)

def draw():
    if mouse_is_pressed:
        fill(random_uniform(255), random_uniform(127), random_uniform(51), 127)
    else:
        fill(255, 15)

    circle_size = random_uniform(low=10, high=80)

    circle((mouse_x, mouse_y), circle_size)

def key_pressed(event):
    background(204)

run()

Expected behavior:

Actual behavior
Window opens, but no drawing occurs

This looks like #10 again! Can you try running one of the test-sketches from that issue and see if you get similar results?

Hi @abhikpal it looks a bit different... no drawing at all...

[abhikpal]

Hmmm.. okay. This looks new. Let's see if more people can reproduce this.

I get exactly the same: a blank window pops up, of the correct size, but no actual animation. However, for me the window that pops up is pure black. mouse_x and _y print out fine and update continuously. Changing background() has no effect. frame_count and focused both give the expected and correct output.

Expected behavior:
First example on repository Read-me
Actual behavior
Pure black window opens, but no drawing occurs

UPDATE: The "error" message disappeared for me after running the command mentioned in this thread: https://stackoverflow.com/questions/18733965/annoying-message-when-opening-windows-from-python-on-os-x-10-8
However, all the other behaviour is still the same.
