Yes, currently you can only report bugs on discord server in #oot-bug-smashers channel. Keep in mind that work on current runtime is mostly stopped and all focus is on big engine upgrade that will come out next year so I’ll only fix if you can provide enough information and it’s relatively simple. There is a good chance this is a problem with Unity itself because the only thing that game does on focus change is muting sounds if that setting is enabled and also stop handling mouse events except for scroll (so that clicks that return focus to window would not be handled by the game).
