Hello    I tried installing Phaser on localhost and tested example games.   Breakout and Tanks game background seems to be shaking all the times (tested in Mac OS Chrome and Firefox). In Chrome, I also experience blinking background in both games.   What is the cause of this issue and is it possible to fix this in the current version of Phaser?   *UPDATE* After I tried other demos, it seems to be 'Tiling Sprite' that cause the problem. Not sure if it is problem with hardware?   *UPDATE 2* Just download latest version of Phaser and this problem should disappear.
