OK, Agree with you. How about check the value like the below? (Return NULL when error happens in gdk_gl_context_realize. It's different from the original.)

I think it is OK. > (Return NULL when error happens in gdk_gl_context_realize. It's different from the original.) Don't familiar with the internal of how gtk-gl work.
