i see. (since there are no speakers connected, i didn't hear...)
i completely missed the pix_snap/pix_data part.

anyhow.

when doing stereoscopic rendering, each [gemhead] will emit 2
rendermessages per cycle.
the first message is for the left eye, the 2nd is for the right eye.
the result you get are for the 2nd eye, since you simply overwrite the
1st value you get.
so: by intelligent use of [spigot]s, [delay]s and whatnot you can make
sure that only the left (first) view is taken into account (before the
annoying rectangle is rendered).

the even simpler alternative would be to change the rectangle:
either make it a rectangle outline (so the actual values are still
visible), or move it a bit, so the pixels read are "just" visible...
