You will need to reinitialize your OpenGL pipeline again, load textures etc. See "User Note 2:" on the SDL wiki here; http://sdl.beuc.net/sdl.wiki/SDL_SetVideoMode > > Also does the sdl:sdl-doublebuf flag when creating a window work the > same way with an opengl window as with a normal sdl window? No, that is to be used only for SDL surfaces. To enable OpenGL double buffering, use; (sdl:set-gl-attribute :SDL-GL-DOUBLEBUFFER 1) Set your OpenGL attributes prior to calling WINDOW. - Luke _______________________________________________ application-builder mailing list application-builder@lispniks.com http://www.lispniks.com/mailman/listinfo/application-builder
