Jit.world and anti aliasing

Hello,
I must miss something but I can't deal with aliasing with jit.world.

First I set up my jit.world to go full screen and I checked the fsaa box. This way I could use cornerpin without noticable aliasing on the edges. But I've got low framerate.

As I red somewhere that with a jitter window properly dimensioned I could have better fps than with fullscreen mode, I've gone this way, and it works.
But I've got very noticable aliasing and I don't find how to fix it...

I'm playing 1920 1080 video files, photo-JPEG or H264, VIDDL engine, Max 7.3, Mac OS 10.11 and Win 8.1.

Thanks.
Alain
