Wayland will sometimes send empty resize events (0 width and 0 height) to the client. I have not worked out the exact conditions a client would receive these but I can assume it might be if the window is offscreen or not mapped yet.
This causes issues with some SDL clients as they receive the 0x0 event and unexpected resize event or might not request to resize back to the correct size.
As per the wl_shell Wayland spec configure events are only a suggestion and the client is free to ignore or pick a different size (this is how min/max and fixed aspect ratio is supped to be implemented).
A patch is attached but is just the first iteration and I will fix any issues such as checking for FULLSCREEN/MAXIMIZED or RESIZABLE flags unless someone else fixes this first.
I have update to take into account non resizable and fullscreen windows. Also adding in maximize/restore and title functions for Wayland.
Generate the C protocol files from the protocol XML files installed by
wayland-protocols, and use them to implement support for relative pointer
motions and pointer locking.
Note that at the time, the protocol is unstable and may change in the future.
Any future breaking changes will, however, fail gracefully and result in no
regressions compared to before this patch.
This will be used by Wayland compositors to match the application ID and
.desktop file to the SDL window(s).
Applications can set the SDL_VIDEO_WAYLAND_WMCLASS environemnt variable
early in the process to override using the binary name as a fallback.
Note that we also support the SDL_VIDEO_X11_WMCLASS in the Wayland
backend so that if a program correctly associated the desktop file with
the window under X11, only a newer SDL would be needed for it to work
under Wayland.

The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
