After returning the Minecraft, after accessing the iOS 11.0 (and 11.0.1) control center (via Home button press on iPad Pro 10.5), items (usually up to two, and always one after the other) from my inventory begin dropping. I am not sure if the items being dropped are selected randomly, but if you pick them back up, the same ones continue to drop. However, I have had different ones drop upon duplication of the issue.

I will try my best to explain what happens. The item, in the inventory bar (while the inventory is closed) will begin filling up with a green bar (within the item box). Once the green bar is full, the item will drop and a second item will start. I think it only ever drops two items. The items being dropped are not necessarily the one that is currently equipped.

I think the issue may be triggering when I change the iPad Pro volume within the control center. I was able to stop this issue by returning to the control center, although that did not work on every occasion.

I have made a video recording, of the issue, on my iPad Pro. If possible, I will find a way to get it from my iPad Pro and link it here.
