A variable controlling whether all window operations will block until complete.
Defined in <SDL3/SDL_hints.h>
#define SDL_HINT_VIDEO_SYNC_WINDOW_OPERATIONS "SDL_VIDEO_SYNC_WINDOW_OPERATIONS"
Window systems that run asynchronously may not have the results of window operations that resize or move the window applied immediately upon the return of the requesting function. Setting this hint will cause such operations to block after every call until the pending operation has completed. Setting this to '1' is the equivalent of calling SDL_SyncWindow() after every function call.
Be aware that amount of time spent blocking while waiting for window operations to complete can be quite lengthy, as animations may have to complete, which can take upwards of multiple seconds in some cases.
The variable can be set to the following values:
This hint can be set anytime.
This hint is available since SDL 3.0.0.
