[osg-users] setGLExtensionFuncPtr priority

[Robert Osfield]

Hi Juilen,

This sounds like a driver bug.  What OS/hardware/drivers are you using?

It would be worth printing out the address returned for each the
"glGetTextureHandle", "glGetTextureHandleARB","glGetTextureHandleNV"
variants to see what is being returned, this might gives some clues
that could help the driver developers track down the issue.

Robert.
