ISSUE
Fake (empty) notification appears when I exit a game after some time of playing. It should appear only when I unlock some trading cards etc. But it's empty but showing as green new notification.

OS
Windows 10

STEPS
Play a game (I'm completing Batman Arkham Knight now) for some time
Exit a game

RESULTS
You'll see the green notifications button as having active new notifications. But there aren't any notifications. It opens empty.

EXPECTED
You don't see any fake notifications in this case
