Hiding the cursor doesn't appear to work reliably on GNOME when another window
steals mouse focus right as we call SDL_ShowCursor(SDL_DISABLE). This can happen
when the keyboard shortcut inhibition permission prompt appears in response to a
call to SDL_SetRelativeMouseMode() with SDL_HINT_GRAB_KEYBOARD=1. The result is
that the default cursor is stuck locked in position and visible on screen
indefinitely.
By redrawing the cursor on pointer focus enter, the cursor now disappears upon
the first mouse motion event. It's not perfect but it's way better than the
current behavior.
Use zwp_keyboard_shortcuts_inhibit_manager_v1 to allow SDL applications
to capture system keyboard shortcuts like Alt+Tab when keyboard grab is
enabled via SDL_HINT_GRAB_KEYBOARD.
Existing SDL applications may not know about the need to set a specific
hint to enable rumble on PS5 controllers, even though they may already
set the equivalent SDL_HINT_JOYSTICK_HIDAPI_PS4_RUMBLE hint for PS4
controller rumble support.
Rather than requiring those developers update their apps, let's use the
SDL_HINT_JOYSTICK_HIDAPI_PS4_RUMBLE value as an indication of the behavior
they are expected for all PlayStation controllers.

Read callback may fire itself on its own even after its been requested
to stop and exactly before the calling code waits for its completion in
indefinite loop. Explicitly preventing re-fireing the submission loop
fixes the issue.

I'm testing with DualShock 4, DualSense, Switch Pro Controller, and PowerA Switch Controller.
I'm using the standard mapping file from here:
https://raw.github.com/gabomdq/SDL_GameControllerDB/master/gamecontrollerdb.txt
With SDL_HINT_GAMECONTROLLER_USE_BUTTON_LABELS turned off (set to "0") I expect the button positions to be the same on all devices, based on Xbox controller button naming (eg SDL_GameControllerGetButton(g, SDL_CONTROLLER_BUTTON_Y) gives me whether the North face button is pressed).
However, the Switch Pro Controller layout is wrong (matching labels rather than positions, so X and Y are swapped and A and B are swapped). And with the PowerA controller the East and West buttons are correct, but the North and South buttons are swapped instead.

Also seeing this on 2.0.14. This is most likely a regression, since we weren't seeing this on an earlier SDL version.
I suspect it might be caused by this commit:
a569b21188 (diff-da9344d94c66b8c702a45e7649f412039f08bba83bd82de33f5c80ea9c8c39d5)
It seems like both the HIDAPI driver and SDL_gamecontroller.c will try to swap the buttons if the hint is set to 0, causing the button remap to cancel out.

This is related to Bug 5034, but crashes under a somewhat different condition.
In the latest tip (changeset 13914) or with the SDL 2.0.12 source + David?s 5034 patch, unplugging and then replugging in certain controller types on macOS will crash. A mix of new controllers like Switch Pro, PS4 and Xbox One all work without issue. But if a controller without a rumble function, like many SNES retro USB gamepads, is mixed with a PS4 or Switch Pro controller it will crash.
File: joystick/darwin/SDL_sysjoystick.c
Function: static recDevice *FreeDevice(recDevice *removeDevice)
On line 159: while (device->pNext != removeDevice) {
Causes: Thread 1: EXC_BAD_ACCESS (code=1, address=0x188)
This can be reproduced in testgamecontroller" by starting the test program with both a ?retro? controller plugged in and a ?modern rumble? controller (Switch Pro/PS4). This may crash on launch, but it depends on which controller ends up as device 0. If it doesn?t crash, unplug the ?modern rumble? controller and plug it back in.
Some of the "retro" controllers I?ve seen this crash with:
- iBuffalo SNES Controller
- 8Bitdo SN30 Gamepad (in MacOS mode)
- Retrolink NES Controller
- HuiJia SNES Controller Adaptor
The issue appears macOS specific. Seen on 10.12.6 and 10.14.6. Not seen on Windows 10.
The while loop in FreeDevice() assumes that every device is not NULL.
recDevice *device = gpDeviceList;
while (device->pNext != removeDevice) {
device = device->pNext;
}
device->pNext = pDeviceNext;
So maybe we should check for NULL here? Or instead prevent adding NULL devices to the list in the first place? Checking device for NULL before entering the loop appears to work.
recDevice *device = gpDeviceList;
if (!device) {
while (device->pNext != removeDevice) {
device = device->pNext;
}
}
device->pNext = pDeviceNext;

In some cases, need create EGLWindow with SDLWindow. In X11 i can get pointer to NativeWindow from **struct SDL_SysWMinfo wmInfo**
```C++
struct SDL_SysWMinfo wmInfo;
SDL_GetWindowWMInfo(ptSDLWindow, &wmInfo)
#if defined(__unix__) && defined(SDL_VIDEO_DRIVER_X11)
nativeWindow=(EGLNativeWindowType)wmInfo.info.x11.window;
nativeDisplay=(EGLNativeDisplayType)wmInfo.info.x11.display;
#endif
```
than i can create EGLSurface
```
eglCreateWindowSurface(nativeDisplay, EGL_CONFIG, nativeWindow, SURFACE_ATTRIBUTES);
```
in Wayland i can do it with same way, just need pointer to **EGLWindow**, we already have pointer to **wl_display** from **SDL_sysWMInfo**, need add to **wl** struct in SDL_SysWMInfo another pointer to **struct wl_egl_window *egl_window;**. And in wayland backend, in function **Wayland_GetWindowWMInfo** return pointer to **egl_window** from **SDL_WindowData**
Now i use patched statically built SDL2 in port of Quake 2 GLES2 for SailfishOS (it use QtWayland):
link to SDL2 commit and changed string for patch:
- 6858a618cd
- b1e29e87b9/SDL2/src/video/wayland/SDL_waylandwindow.c (L463)
link to use in Quake2 port:
1. here i get pointer to EGLNativeWindowType: 6d94fedb1b/Engine/Sources/Compatibility/OpenGLES/EGLWrapper.c (L319)
2. then use it for create EGLSurface: 6d94fedb1b/Engine/Sources/Compatibility/OpenGLES/EGLWrapper.c (L391)

This patch adds a written-from-scratch WSCONS driver for OpenBSD. It does not have hardcoded keymaps, and it features mouse support when wsmux is available.
For this to work, it needs access to the /dev/wskbd* devices which are not available to non-root users by default. Access to those can be granted by changing /etc/fbtab to give the logging user the ownership of those devices.
