[PD] Gem: pix_motionblur interferes with pix_buffer

[Max]

Hi list,

in a Gem patch i use pix_motionblur and pix_buffer and after some time with the pix_motionblur added i can't get rid of it any more. Setting the blur to 0 to the right inlet or switching the motionblur off by sending a 0 to the left inlet doesn't take the blur away any more. only re-loading the videos to the buffer makes the image unblurred again.
It seems like pix_motionblur alters the images which are stored in the buffer.
Sorry i can't provide a simple patch demonstrating the problem right now, but maybe even this rudimentary description is enough to give me a clue what the reason for this behavior could be.

thanks,
m.
