Test script: p5-examples/basics/form/shape_primitives.py

Expected behavior: primitives_expected-1

Actual behavior: In more complex sketches involving moving graphics, objects in which are moving begin to glitch at random intervals rather than the sketch turning to black periodically. primitives_actual

Note: I'm unsure if this is an upstream issue or not, but I've only begun seeing it with p5 so far.

Errors produced (if any): None

Python version: Python 3.6 Operating System: Arch Linux (4.14.10-1-ARCH x86_64)

Fortunately, the issue had a simple solution. It was only a matter of turning on vsync during the creation of the pyglet window in p5/sketch/base.py.
