Hey,
I have just noticed that the Alt-Tab window management key combination does not do its job of switching windows on X11 (with the Unity shell on Ubuntu 12.04), in case window input is grabbed for a fullscreen window using SDL_SetWindowGrab. The reason: Keyboard input is grabbed. At least, you cannot change to a different window using Alt-Tab, although other key combinations used for desktop/window management seem to work (like Ctrl-Alt-RightArrow for changing to a different workspace). This post is also (sort of) an attempt to reply to an older post on the list, which also had a minor patch. A copy of the patch, along with the original post, may currently be found here (yeah, the "bin" file should be opened as a textual one): http://comments.gmane.org/gmane.comp.lib.sdl/56621 In case you don't trust this, I have also attached a copy of the patch to this mail (using what is apparently the original filename). Apart from this patch, there is a problematic workaround I can suggest: Call SDL_SetWindowGrab(SDL_FALSE) if the window is fullscreen. There is one limitation with that (which may not be the only one): If SDL_SetRelativeMouseMode(SDL_TRUE) has also been called, then no relative mouse motion event arrives while a mouse button is pressed. I can't tell for sure what's the case with SDL_FALSE, as it's less relevant.
