Hello, when I run the pixijs tutorial on the following page I can´t see the turning bunny. http://www.goodboydigital.com/pixi-js-tutorial-getting-started/ There is only the green canvas but nothing inside. When I hit F5 to refresh the page the bunny appears. In FF or Chrome everything works fine. This failure happens only in IE11. Is there a workaround to avoid this? Thanks!
