this is because [pix_info] will output information on the "pix" (that 
is: image-data in main memory) in the gemchain.
since you don't have a "pix" in the chain, you get invalid data.

anyhow, the information about width/height should be set correctly in 
the texture-message you send to the right inlet of [pix_texture].

iirc, there is indeed some bug in there with the framebuffer-objects 
(have to check again whether i tried to fix it...)


as a workaround you can use something like:

             |
             [$1 <width> <height> $4 $5 $6(
             |
[pix_texture]

(or the like, i don't remember the arguments of the texture-message by 
heart, just print them to see what you are doing)
