[Bug 941826] Re: OpenGL backend not working with Nvidia driver package

[Peter Würtz]

Workaround:
The shader creation problem completely vanishes when importing PyOpenGL additionally to PyQt. It doesn't even matter if it's imported before or after PyQt, just before the first shader is created.

When I add:
from OpenGL import GL
the example from my first post works.

Someone from the PyQt mailing list suggested that this is caused by an
error when python dynamically loads the GL library.

** Summary changed:

- OpenGL backend not working with Nvidia driver package
+ PyQt cannot compile shaders with Ubuntu's Nvidia drivers
