Anyone else noticed this controller bug?

That plane has trims - but I presume you mean you move the stick around gently near the center at the same time as described in the reproduction steps and yet it flies absolutely straight, even in time accelleration.

As you said though, you followed the instructions and could not reproduce what I see. That's good enough for me.

I presume the steam version (which is the one I bought) of IL-2 is somehow defunct, as that's the only thing file wise that can differ between us presuming a clean install and all.

In the example you provided, it could be either way, because the P-80 has aileron and rudder trim (if I'm not mistaken). If you are trimmed to fly straight with stick centered, it would be that with the bug just the same.

I can't try your example because my G940 slop prevents the stick from being completely centered without a hand holding it there (and it's hard to do it continously as there's no tactile feedback). I did see the stick move in the cockpit and the plane reacted even though sensitivity was set so that no movement was supposed to be possible.

The P-80 control stick moves very noticably with the bug btw. Try setting ALL the sensitivities for pitch and roll to zero in IL-2 and step into the P-80 cockpit. Surely the in-game stick should then under no circumstance be able to move. If you have the bug, then the stick can be seen moving forward (when the Y axis of the joystick hits center) and left (when X-axis touches center) as long as the real joystick is centered. So moving slowly over the center point of the real joystick should make the cockpit stick move left-right, forward-back etc slightly but noticably if you keep camera focused on it.

Note that if you have a well centered spring joystick (for example), the first thing you are likely to notice is that the in-game stick moves to the right and backward a bit whenever you move your stick from center.

Give me a moment and I will record a brief replay displaying how it looks like, then upload.

I recorded the control column/stick moving by itself even though sensitivities were set to 0 - to find that the replay doesn't show it moving. Isn't that AWESOME? All I could record was a stupid looking high speed replay of a 262 slightly changing roll direction and pitch even though the control column isn't moving. Not even going to bother showing such junk.

Tried your P-80 example. Without touching any trims what so ever it has a phugoid oscillation up and down (which is not important). But yes, moving the stick over the center position makes the in game control stick move as I have described, moving the plane accordingly (slight left/right roll, and some minor pitch change, visibly quite clearly when time accelerated).

I think I have just about had it with trying to get anywhere with this bug. I'm going back to disabling all the in-game curves and just using external programs to tweak curves with, that way no bug and no more nonsense. That it didn't even record on replay was the last straw.

Thanks for testing and checking it out. No idea who else is affected and what causes it but it is small enough not to be noticed by most anyway, so I'm betting it will never be officially recognized or fixed.

Yes, it can visibly be seen, although not 'stare you in the face' obvious due to the small amount.

I made a typo in the fig.2 illustration. It should read "underneath green", not red.

I set the roll and pitch axes of my stick to 50% dead band (in IL2), no filtering, and all 100% sensitivity sliders. I saw the green square move in the input setup section, for both roll and pitch, when the real stick was crossing the centre.

I then watched a Beaufighter's and P-51's stick when on the ground, and could not see any movement at all in the column/stick, when doing the same movements as above.

I use a 4096 step BU0836A and hall effect sensors. Due to it's long throw, I normally use 100% sensitivity and no filtering, and have noticed (when keeping the wings level) that IL2 has a noticeable step around joystick-centre, when at any other position, it a tiny joystick movement yields a tiny in-game joystick movement. I've always thought something was a little wrong... along with the strange interpretation of power/pitch axes (I know from DIView that the stick is giving 4096 steps for these axes as well, yet IL2 gives me 2-3% increments).
