But when does that happen exactly? Windows (as in "the operating system") switching window (as in the frames open) focus is not something the game does by itself.
I was building a v6 very simple it was all made it did it in test mode it was default bore and stroke quality was at max as soon as game starts it looks like two window come up
The black window should be there all the time from startup of the game, but it should not get pushed to the front. As long as we don't get a way to reproduce this behaviour, there is nothing we can do about it.
Well, nothing specific really if the game is working as intended is there anything wrong IN the game when that happens? If not, then it's fine. There are plenty of warnings in the game log that don't mean much anymore.
