The GL Renderer current context tracking fails when one window is used with an SDL renderer but another separate window is used with a user handled OpenGL context.
Attached is a small program that reproduces this bug, at least in some Linux machines where an OpenGL renderer is provided by default.
Expected Output:
-"First window" should be blue.
-"Second window" should be green.
Gotten Output:
- "First window" black.
- "Second window" blue.
What happened:
The renderer created for the "first window" ends rendering into the "second window" OpenGL context.
Bug location:
SDL_render_gl.c - line 286 on hg:
static SDL_GLContext SDL_CurrentContext = NULL;
When making SDL_GL_MakeCurrent from the user perspective, that variable or the GL renderer is not notified about the OpenGL context change.
Solution proposal:
- Move the current GL context cache into another place global.

Attached is patch from the OpenBSD ports tree to add 24-bit support to the sndio backend and to make use of the sio_open() option SIO_DEVANY.

The Xcode Instruments Leak tool reports a leak from IODisplayCreateInfoDictionary in Cocoa_GetDisplayName.
This happened after upgrading to Xcode 5.

Add a gamepad mapping entry for Bluetooth DualShock 4 controllers on Linux.
The button mapping is the same as the USB controller, but the GUID is
different.
It was simpler to just have the polling (actually: hotplug detection)
functions return immediately if it's not an appropriate time to poll.
Note that previously, if any joystick/controller was opened, we would poll
every time anyhow, skipping this function.
This makes the X error handler used for GL context creation handle *all* errors
and provide the user with specific error messages when SDL_GL_CreateContext
fails.

Patch to fix the y component of the position of fullscreen windows in OS X.
In Mac OS X with the latest Mercurial code, when a window is in exclusive-fullscreen the y component of its position is offset by the same amount that is normally taken up by the menubar, resulting in a black bar at the top of the screen.
The recent changes to the internal ConvertNSRect function make it treat the bottom of the menubar as 0 for the y component of window positions, even when the window is fullscreen and 'above' the menubar.
I have attached a patch which fixes the issue by only making the window position relative to the menubar in windowed modes.

Steps to reproduce:
- Run testwm2 app in the SDLTest Xcode project
- Press Control+R to enable relative mouse mode. The mouse cursor should disappear.
- Press Control+Enter to enter fullscreen.
- Expected: a black screen with no cursor visible. Observed: a black screen, but the mouse cursor is visible in the middle of the screen. It doesn't move when I move the mouse.
Reproduced with latest sdl2 hg (changeset 29aac8b813d9) on OS X 10.9.2. Can't reproduce the problem on OS X 10.6.8 or 10.7.5.
I'm speculating that this really an Apple bug.. but anyway, the attached workaround seems to fix it for me, and I think it's fairly safe.
A more obvious idea, sticking a call SDL_SetCursor(NULL) at the end of Cocoa_SetWindowFullscreen, didn't work.

The problem seems to be the spaces handling code in -setFullscreenSpace: (SDL_cocoawindow.m) is incorrectly reporting that the SDL_WINDOW_FULLSCREEN -> windowed transition has already happened.
i.e. I saw this case was getting hit when trying to leave SDL_WINDOW_FULLSCREEN:
"else if (state == isFullscreenSpace) {
return YES; /* already there. */
}"
With the attached patch, both Control+Enter (SDL_WINDOW_FULLSCREEN toggle) and Option+Enter (SDL_WINDOW_FULLSCREEN_DESKTOP toggle) work in an sdl test app (I tried testwm2). Tested on OS X 10.9.2.
