See for further information above mentioned radar. 
In the mean time I have found a way to reproduce this issue onder very specific circumstances.

See updated steps to reproduce below:

Steps to Reproduce:

2. Wait until MBP goes to sleep or close lid
3. Open lid or wake MBP

See attached pictures taken from the login screen.
