Thank you. I still don't understand what caused that problem in the first place, though. > > ok the npot2 extension could lead to a driver crash because it is quite > new and perhaps buggy.

And I still have no idea why :) I agree that setenv OSG_IGNORE_EXTENSIONS GL_ARB_texture_non_power_of_two should have the same effect as removing line 971, but it still does not help. My graphics driver is a prime suspect of mine as well. I have seen graphics drivers cause weird problems like this in the past. Hopefully there will be an update soon....
