Hi Robert,
What extra info do you need, other then the size of the image that I
feed into the ImageStream? For the time being, it is working for me as
it is right now.

Hi Raymond,
I am the one who implemented the PBO support, and the last time I used
it worked fine (under Linux). I wouldn't expect it to add an extra
size constraints. Perhaps its a driver issue, perhaps a portability
issue. There is way too little info to understand what might be amiss
so I can't really comment further.

Hi Robert,
Hmm, I thought so too. It's not the texture functionality itself, it is
(most probably) the pbo code that is causing the trouble. When I pretend
that I am an Apple, i.e. the computer ( :-P ), and thus comment out the
usage of the pixel buffer object, it runs fine.
This is all done on a modern nvidia (don't have access to the details
right now), on windows, version 1.2 I believe (so not the cvs
version). I
will look into it some more when I have the time. Do you have any
ideas in
the mean time?
best regards, thmx!
