Whoops, sorry, Xavier was right - you don't need to reinitalize video subsystem, just call SDL_SetVideoMode and it should be fine. I've checked it few minutes ago with my engine and it worked. However...

... after toggling fullscreen, textures were deleted. First I thought there's sth wrong with my code, but then I found this:


So, OGL context is destroyed => textures are deleted => you have to reload them :-/
