[PyOpenGL-Users] Works on OSX, fails on Linux

[Derakon <de...@gm...>]

I'm trying to port a program from OSX to Linux, so it can be run over
an SSH tunnel. I'm getting "invalid operation" errors when I call
glTexSubImage2D, though. I've trimmed the program down to a
more-or-less minimal program (still almost 200 lines) which still
exhibits the failure:

http://paste.ubuntu.com/611982/

Dependencies are PyOpenGL, numpy, and wx. I apologize for the very
inconsistent code style/formatting; this is a bit of a hodgepodge and
I'm cleaning it up as I get the chance.

I've pasted the error I'm getting at the end of this message. It's
occurring in some PyOpenGL-accelerate code. From my understanding,
this package isn't actually necessary; it just makes certain
operations faster. Is it possible to uninstall it? Googling around
doesn't show it being particularly straightforward to uninstall Python
packages, but perhaps this one's more self-contained?

Could it be that running over ssh -Y is what's giving me trouble? I'm
not really familiar with SSH tunneling in general and what it does to
the display. Before I started trimming down the program to make the
"minimal" version, I was actually semi-randomly getting assertion
errors in /usr/lib/libxcb-xlib.so (and when the assertions didn't show
up the app would just hang with nothing displayed).

Anyway, here's the error. Any advice would be appreciated. Thanks!
