SDL3: SDL_render_gl(render name: opengl) dose not support transparent on Linux/X11 (Bug #11273) (#11274) 
SDL3: SDL_render_gl(render name: opengl) dose not support transparent on Linux/X11:

Create SDL window with SDL_WINDOW_TRANSPARENT flag;
Create "opengl" renderer for the window;
The window can't shown with errors:
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 130 (MIT-SHM)
Minor opcode of failed request: 3 (X_ShmPutImage)
Bug reason:
SDL_x11window.c:490 : bool X11_CreateWindow(SDL_VideoDevice *_this, SDL_Window *window, SDL_PropertiesID create_props)
SDL_x11window.c:566 : vinfo = X11_GL_GetVisual(_this, display, screen, transparent);[XVisualInfo *vinfo]
the X11_GL_GetVisual function returns a vinfo dose not support transparent.

Fix:
SDL_x11opengl.c:637 : XVisualInfo *X11_GL_GetVisual(SDL_VideoDevice *_this, Display *display, int screen, bool transparent)
X11_GL_GetVisual should returns a vinfo support transparent when transparent is true.

Simple DirectMedia Layer (SDL) Version 3.0

https://www.libsdl.org/

Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.

More extensive documentation is available in the docs directory, starting with README.md. If you are migrating to SDL 3.0 from SDL 2.0, the changes are extensively documented in README-migration.md.

Enjoy!
