Ah. You are running at 60 fps? You can do a simple toggle to only render the video every other frame using a simple [spigot] and counter. Just setting a simple motion or not state is best done at a much lower rate otherwise you have to filter the results anyway.

I used pix_movement and blob for basic motion detection for years. I
gated the video signal so it would only output every half second or
second
Yes it does help, it fixes the problem completely. But that is not an option if i need to produce graphical output at a higher framerate. It's ok to detect the movement at a rate equal to or lower than the camera frame rate, but i can't lower the whole gem framerate because that will affect video output.
Try setting the GEM framerate to the
advertised frame rate of your device and see if that helps.
