Strange .. History of fx, one time it's Ok on Firefox but not on Chrome.
The other time it's ok on opera not good on safari this is never ending story.
The solution is to once and for all to put any browsers in the trash.
Looks like the question of incompatibility is wanted. And that small developers like me will break the head during nights .
The developpers of these browsers are true incapable. it's been years that they have not managed to find a standard regarding eg html5. I would not talk about shaders !
I am waiting chrisbrobs release...
