The Wayland backend lacks pointer warp functionality, so special-case the relative warp mode hint to deliver accelerated relative motion deltas, which is ultimately what the client wants by enabling this hint.
I found if I try to make texture bigger than screen and use it as a frame buffer, it gets cuts of content. To ensure that render will be valid, I making sure scissors were initialised properly.
P.S. This works on hardware, however, emulator PPSSPP seems has a bug in this case, so I going to report that and making the simple demo.
Since it's no known way to use genuine viewport with PSP SDK, I implemented the workaround using manually added/subtracted offsets to vertices passing to the render API. To assign viewport and cliprect in valid way, I copied part of code from the Vita's module and adjusted it to work on PSP.
VMware relies on the cursor being set to NULL to optimize relative mouse motion for games.
We should also revisit whether current RDP works better with a NULL cursor or a transparent cursor.

The comment in the source wasn't true; PipeWire doesn't _have_ to work in
float format. It presumably does if it has to mix, but if a game is the only
thing making noise on the system--a common scenario--then it might be able to
pass, say, Sint16 data straight through to the hardware without conversion.
Fixes#12129.

On newer systems, the trick isn't necessary, and if you do it, if the user is
moving the mouse when launching the app, it'll show a hidden Dock.
Fixes#10340.

SDL_PrivateJoystickAdded was called before setting the InstanceId in the adapters ctx->joysticks array. This would eventually broadcast the SDL_EVENT_JOYSTICK_ADDED event with the new InstanceId, if your program listens for the added events and opens joysticks at that point it would always fail because there would be no matching InstanceId in the ctx->joysticks array.

The SIGILL handler is not very reliable and can cause crashes.
Linux provides the CPU's AltiVec support status in getauxval.

Unregistering the input report callback marks the device as disconnected, so IOHIDDeviceClose() would never be called if the device wasn't already disconnected when hid_close() was called.

It looks like both macOS (15.1.1) and SDL are trying to talk to the controller at the same time, which can cause interleaved replies or even locking up the controller. Waiting a bit before talking to the controller seems to take care of this.
On Windows 11, apparently HidD_GetManufacturerString() and HidD_GetProductString() can return TRUE without actually filling in any string data.
