SDL2: Mac inaccurate display count after disconnection / laptop close

[silbinarywolf]

SDL2 version: 2.30.5 MacOS: Sonoma 14.6

How to reproduce

• Have a Mac laptop open with external display connected
• Run application
• SDL_GetNumVideoDisplays will report two displays
• Close Mac laptop
• SDL_GetNumVideoDisplays will still report two displays
• Calling SDL_GetDisplayUsableBounds for display 0 will get the dimensions of the laptop but placement will still be on the monitor
• Calling SDL_GetDisplayUsableBounds for display 1 will get the dimensions of the monitor

What I expect

• SDL_GetNumVideoDisplays to report one display after I close my Mac laptop / "disconnect" that display
• SDL_GetDisplayUsableBounds to return the actual monitors dimensions for monitor 0

Other notes

• If I restart the application after disconnecting the display (closing the laptop) SDL_GetNumVideoDisplays will report one display
