Anyone seeing a strange white rectangle drawn in the Phaser game canvas in Google Chrome (Version 56.0.2924.87 (64-bit)) WebGL mode on OSX Sierra (10.12.3)? https://phaser.io/examples/v2/buttons/action-on-click I thought that it was just me having the problem. I am not using WebGL / auto as a temporary work around. Other Phaser examples I have seen are working fine.
