If I set the blend_enable to 1 I get no output, no matter which blend mode I try.

I’m using Jitter(demo mode) inside M4L, running Windows (Boot Camp) on a Macbook Pro 8600M GT.

If I set blend_enable to 0 or use a different mac it works fine.

Is it user error (quite likely!) or does the card not support blend modes or something?

Thanks

This will set all alpha values to 1.
