Tough the UI is active, movement and rotation is allowed, meanwhile placing or breaking blocks is not.
Doesn't look like that one either, basically when i try to pause the game neither UI doesn't show up, just blank with the game still running like in java when you turn of the UI-s for screenshots
Yes, the only difference is the missing loading bar
Yes, that fixed it. I forgot to comment that, the texture pack(s) was/were the issue, curiously prior versions worked fine with them.
