Recently, a problem cropped up in PyOpenGL–namely that it wouldn’t raise OpenGL errors as exceptions (PyOpenGL checks with glGetError after every call).
I realized that it wasn’t just PyOpenGL. I wrote a C++ program, and glGetError constantly returns 0 (even after glViewport(0,0,-800,-600), etc.). My test applications had valid contexts, etc., and worked as expected for other people.
So, apparently, my problem is specific to me. I’ve tried everything I can think of–including rolling back/re-updating video card drivers.
Any hints at all???
