Description Ellie 2018-08-23 18:42:42 UTC 
When an SDL_Window (not full screen, decorated) is visible but in background, first mouse click causes focus gain but no mouse click event. While this can be useful for windowed games, this is highly undesirable and confusing for any other graphical app since nothing else, e.g. anything Qt/GTK+-based, behaves like that.

Can this be turned off? Or maybe remove it altogether, given any game could easily implement to drop the first mouse click that happens less than ~2-3ms after a focus gain event if this behavior is desired.

Yes, you can set SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH to "1"

Oh sorry, seems my google-fu failed me there. Sorry about the unnecessary ticket!
