Discolored output with vf_gradfun and nv12 pixel format

ffplay xtest720.mkv -vf format=nv12,gradfun=32:32,format=yuv420p

My conclusion: vf_gradfun actually supports only strictly planar formats. nv12 is sort of half-packed (separate Y plain, but packed chroma), and maybe you normally don't see the bad effect on the crhoma so well.

Is this problem only reproducible with ffplay or also with ffmpeg?
Please provide the failing command line together with the complete, uncut console output to make this a valid ticket.

Can you post actual screenshot? I tried here with random video and I can't see anything wrong.
