I tried a couple of times, but I cannot reproduce that problem with the
covering window here (using Linux with XFCE). Maybe it depends on the
desktop environment?

So no clue how to fix that problem... maybe you could try whether it works
any better if you add the new code only to SDL_WINDOWEVENT_LEAVE and
SDL_WINDOWEVENT_ENTER instead of executing it for SDL_WINDOWEVENT_FOCUS_GAINED
and SDL_WINDOWEVENT_FOCUS_LOST, too? ... I doubt that such a change will
help, but it is maybe still worth a try.
