Interesting. The issue occurs because I have WebGL disabled, causing the createShader function you're using to throw an error. You can reproduce this by going to chrome://settings, disabling "Use hardware acceleration when available," refreshing the page, and then triggering the same error.
Sorry for duplicate post. Also this feature is enabled by default, but causes issues with several sites.
