SDL_AddDisplayMode returns an SDL_bool corresponding to whether or not the given display mode was added or not. It will return SDL_FALSE if a matching display mode already exists in the display's list of display modes, which causes ownership of the mode driverdata to remain with the caller. Some video drivers ignore the return value of SDL_AddDisplayMode, so leak the driverdata memory when SDL_AddDisplayMode returns SDL_FALSE.

Here is the bug in latest SDL 2.0.8 development repo. It is obvious and simple to fix by correcting typos on six lines of code.
In src/video/SDL_yuv.c on lines 217, 249, 280, 321, 353, and 384 the wrong conversion functions are called for SDL_PIXELFORMAT_ABGR8888 and SDL_PIXELFORMAT_BGR888. Instead of ABGR functions, BGRA functions are called. These are typos.
New functions get and set the YUV colorspace conversion mode:
SDL_SetYUVConversionMode()
SDL_GetYUVConversionMode()
SDL_GetYUVConversionModeForResolution()
SDL_ConvertPixels() converts between all supported RGB and YUV formats, with SSE acceleration for converting from planar YUV formats (YV12, NV12, etc) to common RGB/RGBA formats.
Added a new test program, testyuv, to verify correctness and speed of YUV conversion functionality.

Remove static int vm_error and vm_event, use local variables instead.
This fixes unused variable errors when compiling with SDL_VIDEO_DRIVER_X11_XINERAMA undefined.
src/video/x11/SDL_x11modes.c:505:22: error: unused variable 'vm_error' [-Werror,-Wunused-variable]
src/video/x11/SDL_x11modes.c:505:12: error: unused variable 'vm_event' [-Werror,-Wunused-variable]

Add support to be able to set EGL_SURFACE_TYPE bits when creating an EGL config. This is usefule when wanting to create pixel buffer surfaces in custom video drivers.

In src\joystick\android\SDL_sysjoystick.c in SDL_SYS_JoystickDetect when SDL_GetTicks return number grater 2147483648 (after 24.85 days uptime) SDL_TICKS_PASSED(SDL_GetTicks(), timeout) return FALSE and Android_JNI_PollInputDevices is never calling.
And in JoystickByDeviceId - when search for newly added joystic - after SDL_SYS_JoystickDetect item not reinitilized, and always stay NULL, cause return NULL instead of added joystick.
Changing the background color causes the titlebar to blend against it on
modern macOS releases, making all SDL windows look wrong by default. This was
set to make the window not flash white before a GL context is ready, but we
can accomplish this in our window's view's drawRect implementation, too.

I noticed that, at least on Intel GPU hardware, passing SDL_RENDERER_PRESENTVSYNC would result on a static console instead of the program graphics.
That was due to the fact that calling drmModePageFlip() only works if we have previously set up CRTC to one of the GBM buffers with a drmModeSetCrtc() call, so now it's done and things work as expected.
The KMSDRM_GLES_SetupCrtc() call is done only one time, only when needed (when egl_swapinterval is not 0: when it's 0, there's no need for it because we flip by calling drmModePageFlip() anyway).
The place where KMSDRM_GLES_SetupCrtc() call is done may look strange, but it's right: it needs EGL completely ready because it needs to call eglSwapBuffers() internally to work (see more comments about it in the code).

Patch that adds [-1, 1] clamping to the scalar audio type conversions.
This may come from the SDL_Convert_F32_to_X_Scalar functions. They don't clamp the float value to [-1, 1] and when they cast it to the target integer it may be too large or too small for the type and get truncated, causing horrible noise.
The attached patch throws clamping in, but I don't know if that's the preferred way to fix this. For x86 (without SSE) the compiler (I tested MSVC) seems to throw a horrible amount of x87 code in it. It's a bit better with SSE, but probably still quite the performance hit. And SSE2 uses a branchless approach with maxss and minss.

Angle supports GLES3 but when using these functions (SDL_CreateWindow and SDL_CreateRenderer), defaults again to GLES2.0.
A current workaround (hack) to retrieve a GLES3.0 context with Angle is:
1) set
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 3);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 0);
after InitSDL AND after calling SDL_CreateWindow (before SDL_CreateRenderer)
2) Comment lines 2032-2044 in SDL_render_gles2.c, funtion GLES2_CreateRenderer
window_flags = SDL_GetWindowFlags(window);
if (!(window_flags & SDL_WINDOW_OPENGL) ||
profile_mask != SDL_GL_CONTEXT_PROFILE_ES || major != RENDERER_CONTEXT_MAJOR || minor != RENDERER_CONTEXT_MINOR) {
changed_window = SDL_TRUE;
SDL_GL_SetAttribute(SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_PROFILE_ES);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, RENDERER_CONTEXT_MAJOR);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, RENDERER_CONTEXT_MINOR);
if (SDL_RecreateWindow(window, window_flags | SDL_WINDOW_OPENGL) < 0) {
goto error;
}
}
This retrives a GLES3 context as confirmed using glGetString(GL_VERSION). This should be fixed by modifying a few if's.

Since changeset 11607:60cd425a2f14, I am getting the following
error upon quit. Running testsprite2, clicking the mouse, and
quiting it is enough to trigger it. This is on my old Fedora9
x86-Linux:
X Error of failed request: BadCursor (invalid Cursor parameter)
Major opcode of failed request: 2 (X_ChangeWindowAttributes)
Resource id in failed request: 0xb057340
Serial number of failed request: 905
Current serial number in output stream: 906
Reverting https://hg.libsdl.org/SDL/rev/60cd425a2f14 removes
the error.
