SDL losing OpenGL Context
Author
Whenever I do an SDL_SetVideoMode() after my program has already set it once, (For a resolution change or to toggle fullscreen.) it loses the OpenGL context and all I get from GL is a black screen and drawing doesn't work.
I've tried restarting SDL entirely, but it just doesn't fix it. Does anyone know a way to get this to work?
When you change resolutions, color depth or what have you, you need to reload your textures, reset your viewport and projection matrix and set all states again.

And I discovered that GLTT is using some sort of texture. I really should've realized this. Thanks.

Looks like you need to also reset all the rendering states. It looks to me like depth testing is disabled (or depth writing is disabled?).
