colors from Label Bitmap Fonts disappeared after Chome browser was updated to version 46.0.2490.71
it is reproduced for colors set from cocos studio and from code(using function setColor)
Perhaps this can be fixed if change in function globalCompositeOperation from "destination-atop" to "destination-in" in file cocos\web\cocos2d\core\textures\CCTexture2D.js:483 (v4.8.1)
