Ah yes, that is most correct. I shall look closer to the activity in the future.
As for the requested debug screen video, it is quite impossible to get at this time. As the game will not respond long enough to get to any of my worlds, let alone a debug screen. Nor can I force the game to crash at this point. I know you didn't request it from me, but since the OP and I seem to have the same issue I figured I might as well try.
I noticed there has not been any activity on this issue in a while, as the moderators have deemed it "Resolved". Has the OP managed to get his game working again, and will Mojang address this issue?
Alright, I have a small update. After running minecraft as an administrator it seems to be working just fine.
