there is currently (and has been for at least a month) a bug where your entire screen shakes/jitters when moving and shooting with haze and sometimes infernus. from what i have heard from other people experiencing this bug it seems to get worse with higher firerate. some people have noticed this issue appearing after watching replays. personally i have unbound replay and still get this bug. on haze i get this bug every single game while on infernus it has happened a few times but not always.
