Hi John,
Thanks for the bug report. On Ubuntu 8.04, I can reproduce this with
PyOpenGL 3.0.0b6, but it is not present with PyOpenGL 2.0.1.09. I can
workaround it by changing VisionEgg/Core.py line 475 to "if 0:" (from
"if gl_version >= '1.2' and hasattr(gl,'GL_BGRA'):").
I'm going to dig deeper and determine if this is a bug with PyOpenGL or
the VE, but in the meantime, that's hopefully enough for you to move on.
I'll report it if it's a bug with PyOpenGL and fix it if it's a bug with
the VE.
