Also, I'd like to see an actual fix for the delayed input rather than a hunch that fullscreen *might* fix it.
It is not a hunch. There is no "*might*", past experiences tell me this. Everyone would like to see an actual 'fix' for this, but I don't see that happening any time soon (the issue was brought up months ago).
Seems like full screen is going to take longer than expected. Hope you guys can get it worked out as soon as possible
