While using the specialist sniper loadout, occasionally I would charge up a shot and try to fire as soon as it was charged. If I did it too quickly this would result in the sniper losing it's charge, no shot being fired, but graphically it would look like I had full charge, the reticule would be full and the gun would be glowing, though there is no beam. This is really annoying because it puts me off-balance and makes it hard to tell when the next shot is ready to fire as I only have the thickness of the beam to go by.
