+1 ... So fed up with this bug. A game breaking issue. It definitely happens with some sort of combo of keys using the scope-in key (for me it's the default mouse right click) at the same time as pressing another key (in my case it appears to be maybe tab, Q or W). Once you get it, it basically means you will keep getting it when you try to scope in (or whatever key is set to scope in). Meaning you cannot scope in for the rest of the game if you don't want the bug to re-occur. Then you are reliant on an enemy killing you and that you're not revived. And if you get the bug when dead... or on any other screen you can't get killed by an enemy to reset it.. you have to alt+f4, losing all progress.
Oh and I should note it has only started happening since the last patch.
