Blank sketch window on Mac about p5 HOT 4 CLOSED

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

from p5.

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.

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...
