Unable to get the Mask on iPad2 working

[Bart]

Hey Guys

 

I'm having trouble with using a mask on an iPad2.

It works fine on any PC, android and even on a macbook, but not the ipad.

 

Using the following code:

this.mask = this.game.add.graphics(0, 0);

this.mask.beginFill(0xff00ff);

this.mask.drawRoundedRect(30, 30, this.game.world.width - 60, this.game.world.height - 60, 10);

this.mask.endFill();

this.mask.name = "Mask";

Any ideas?
