That makes me a little sad.Its a little odd it creates both a compat profile then some core profile threads. It also looks for GL_EXT_framebuffer_object in core but I'm still checking if this is ok to enable, as far as I can tell it should be ok because our core implementation shares objects which is what the EXT implementation is supposed to do. Maybe you could comment of this as it seems you were the last one to edit that code.I'm not 100% sure it's valid to expose either of these extensions on core profile. Pretty much all of these old extensions explicitly allow behavior that was deprecated and removed (e.g., user generated object names). EXT_fbo had some differences with ARB_fbo, so there are some of the entrypoints that aren't shared. I don't know whether or not any of those functions check (or need to check) the extra core profile restrictions.
The spec covers the differences in: Dependencies on ARB_framebuffer_object and OpenGL 3.0It seems like it should be fine to me. The only issue is it says ARB should share across contexts but currently it does. However this is an existing bug.
Do the closed-source drivers expose these legacy extensions in core profile? This seems like a mess...
Yes the Nvidia driver does I haven't checked AMD but I assume it does or the game would have failed to launch there.
