--- Comment #2 from Roderick Colenbrander thunderbird2k@gmail.com 2010-04-28 06:33:23 --- The only place where we are making such call is in surface.c: glTexParameteri(bind_target, GL_DEPTH_TEXTURE_MODE_ARB, GL_LUMINANCE);
Is this the offending call in your case? If it is then I find it a bit surprising since that path is only used when FBOs are around. Do your drivers offer GL_EXT_framebuffer_object / GL_ARB_framebuffer_object? (typically this extension is only around on OpenGL 2.0 capable cards) The code won't be entered if you set the OffscreenRenderingMethod to backbuffer.
