I've run into a little problem and not sure if it is a code issue or driver issue.

When I use SGIS_generate_mipmap and EXT_texture_filter_anisotropic together, my program crashes. But only if I use these two together, if run with one on and other off, it works perfectly (for being in pre-alpha stage).

Any ideas as to why?

Do you have an ATI card?

I have had my problems with ATI and GENERATE_MIPMAP_SGIS too, including crashes.

Specify GENERATE_MIPMAP_SGIS before texture upload and never change it again.

More specifally a FGL8800.

I've tried that...in several different locations in my code (when I detect it, when I change it in my local state machine, and in the image loader before upload). While in the image loader, it crashes using hardware mipmapping, however, when else where the textures appear as though textureing is disabled when it is enabled.

Any other ideas?
