I have used Black Ink on my previous Windows 10 PC and it worked fine.
I recently bought a MacBook Pro and am running Windows 10 partitioned on the drive. When I use Black Ink, the canvas shows up completely black. Every time I draw on the canvas, it reveals the canvas in large glitchy squares and then goes back to black when I stop drawing... I'm not sure if this is because of the new hardware or what.
Also... will there ever be an OS X version of Black Ink?
