I have a problem with the uplay overlay too. When i press shift f2 nothing happens except for my mouse changing to the windows standard until i do something that would remove the overlay. Like if the overlay was invisible. Unfortunately, this is not the only problem associated with it. Another problem is that the overlay is actually turned on and I don't know how I unknowingly spent 350 Ubisoft Units stupidly like this: (((350 Units Ubisoft won't give you back because he thinks you're lying and you're buying things normally, but that's a bug in the game "For Honor" because it doesn't happen in any other game !!!
