I myself am not that well-versed in c and opengl - especially opengl - I
can read and write basic c code but that's my limit.
The problem only appears when using an offset that's not zero.If you want
to debug the issue you could very well use the dolphin-emu and apitrace.
You can find one apitrace here
http://markus.members.selfnet.de/dolphin/dolphin-emu.trace
(~48M)
The only 2 reasons I ever thought of learning more c and opengl were
dolphin and nouveau (what a coincidence).
Hope that could help.
With kind regards,
Thomas Schneider
