Confirmed in 1.8.3. Occurs when switching from any mode, not just creative. Also occurs if you try to break a block with a sword in creative mode.
I can also confirm this issue. Happens for a moment, and then stops.
EDIT: Nice catch, @unknown! Maybe we should create a new ticket for that, or change the summary of this one so it includes that.
Confirmed for 14w21b
