During the Coretech mission to recover the ICPD if I try pickpocketing Luben while sneaking and he notices me while the pickpocketing window is open, after going through the dialogue to get him to leave peacefully, the screen stays black after it fades out. The controls still seem to function, it's just that nothing is showing except for the mouse pointer and tooltips.
It might be a good idea to check whether this happens in other instances where dialogue is triggered automatically upon an NPC spotting the player character and followed instantly by a fade to black.
