[squidbus]

Using SDL 3, calling SDL_StopTextInput from another thread causes the following crash on macOS:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[HIRunLoopSemaphore wait:] has been invoked on a secondary thread; the problem is likely in a much shallower frame in the backtrace'
*** First throw call stack:

libc++abi: terminating due to uncaught exception of type NSException

Would like to ask for one of the following:

• For SDL to handle dispatching the appropriate calls to the main thread to avoid these issues.
• For SDL to document that this function (and possibly related input functions) should be called from the main thread.
