With SDL 2.0.12 under MS Windows, if the window is partially offscreen calling SDL_SetWindowGrab(w, SDL_TRUE) works, but subsequent call to SDL_SetWindowGrab(w, SDL_FALSE) does not work.
I tested this in both real program, and a small test app, where unlocking cursor worked perfectly while window is fully in desktop bounds, but did not work if it was at least few pixels outside.
For the reference, following code is enough to reproduce the issue:
#include <windows.h>
#include <SDL.h>
int WinMain(
HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nShowCmd)
{
SDL_Init(SDL_INIT_VIDEO);
SDL_Window* w = SDL_CreateWindow("", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 640, 400, 0);
bool grabbed = false;
bool want_quit = false;
while (!want_quit)
{
SDL_Event event;
while (SDL_PollEvent(&event))
{
switch (event.type)
{
case SDL_QUIT: want_quit = true; break;
case SDL_KEYDOWN:
if (event.key.keysym.scancode == SDL_SCANCODE_SPACE)
{
SDL_SetWindowGrab(w, static_cast<SDL_bool>(!grabbed));
grabbed = !grabbed;
}
}
}
}
SDL_DestroyWindow(w);
SDL_Quit();
return 0;
}

SDL dynamically loads libusb but does not check the return value of 'SDL_LoadFunction'.
Also libusb is loaded and initialized several time because 'SDL_hidapi_wasinit' is never set to true.
I made a patch if you want to test:
- check that 'hid_init' is called once and only once,
- check return value of 'hid_init',
- check return value of 'SDL_LoadFunction',
- check return value of 'SDL_malloc',
- add some debug logging.
On older mac, where METAL Renderer METAL fails to create, it allows to switch back to OpenGL SDL_Renderer
by re-creating the window (METAL flags was previously persistent).
This can happen if the application has not yet processed SDL_JOYDEVICEADD when
the same joystick is removed. It may also happen if two joysticks are added
and the second joystick is removed before the first joystick's SDL_JOYDEVICEADD
has been processed by the application.

Trying to integrate the latest SDL2 changes into our iOS project of Exult I've stumbled over the fact that when I added the static iOS library the public header files were copied to the archive of our project when you let Xcode build the archive.
This makes the archive invalid for upload to the AppStore Connect.
To fix this you need to delete the public headers from the build phase:
Open the xcode project, select the target "Static Library-ios", got to build phases, and in "headers" delete all the headers in the "public" group. This is safe to do as this actually just copies the public headers for some odd counterintuitive reason.
I think this needs to be done for all the library build targets but likely not for the framework targets.

This is as of commit 50d804ea729accf9e3a9ce83238d0a2976a17545 from https://github.com/SDL-mirror/SDL, which is HEAD as I write (apologies, not confident with Mercurial)
# Config
macOS: 10.14.6 (18G6042)
cmake --version: cmake version 3.16.20200101-g23e782c
clang --version: Apple clang version 11.0.0 (clang-1100.0.33.17)

# Repro steps
Run the following commands in the shell.
cd /tmp/
git clone https://github.com/SDL-mirror/SDL
mkdir build.SDL
cd build.SDL
cmake -G ../SDL/
Examine cmake output.
# Expected result
Metal is detected.
# Actual result
It appears that Metal is not detected! Note this line in the summary:
-- RENDER_METAL (Wanted: 0): OFF
# Fix
Change check_c_source_compiles to check_objc_source_compiles. The cmake script tries to add -ObjC to the clang command line, but, for whatever reason, this doesn't seem to work.
Change the test source to have an empty main. The "return 0;" line seems to confuse cmake somehow, causing it to crap out with an error about HAVE_FRAMEWORK_METAL being an unknown argument. (Maybe I'm just dense, but it's not obvious to me what the problem is here.)
With these two changes:
-- RENDER_METAL (Wanted: ON): ON
Patch attached.

When you unified the Xcode project file you forgot to add the iOS file (/src/misc/ios/SDL_sysurl.m) to the project file, so the dummy in that folder takes over and the call does not work.
Relevant commits:
http://hg.libsdl.org/SDL/rev/c86bbf75f55e (SDL_OpenUrl enabled for macOS/iOS)
http://hg.libsdl.org/SDL/rev/282c3dc1cf65 (and following: unified Xcode project files)
Adding an ios group in the misc group of the project file and then adding /src/misc/ios/SDL_sysurl.m to it fixes the problem.

Currently the rawinput driver always reports a device as "wired". This changes that to "unknown" and updates it once the device is correlated with xinput.
Most of the raw input events are dispatched in the main windows message loop. We only dispatch device change messages separately when we need them to be completely up to date.
