Two handed aiming anomalies that affect all weapons except the pistol and plasma rifle

[slipperfish]

Oddly this bug does not effect the pistol and plasma rifle, but seems to affect every other weapon

When you activate or release two handed grip, your weapon will briefly point at the wrong angle a few degrees for a frame or so before correcting. To easily see this, just point your mainhand controller and offhand controller in slightly different directions and spam two handed grip button and watch the weapon model against a high contrast background, like the AR at the start of the second level. You can also see the problem in the crosshair.

More info:

The misalignment isn't on the path between the one handed cross hair position and the two handed crosshair position, so it doesn't look like interpolation between the two. I also can confirm this bug is in 1.1.0 before weapon smoothing was added

I think this is related to another bug that is a bit more serious and not cosmetic. This also doesn't effect the plasma rifle and pistol, which is beyond coincidence IMO. When you aim with two handed aiming, your point of aim becomes more inconsistent the closer you point to zenith and nadir, and it changes with azimuth. Another way of saying it, take any weapon that's not the pistol or plasma rifle, hold it with two hands, aim high or low, then spin left or right with smooth rotation. Your crosshair will move in a sine wave path instead of a straight circle.

It seems similar to how the rockets have wacky two handed aiming, but it's not as near as bad. Or how weapons misbehave when I change c_ControllerRotation. But unless the player is aiming very high or very low, the problem is subtle.

Also changing the name of this issue to a better description
