Same problem in the developer build of the current release.

I have found the source of this problem; I have the same issue (developer build this post date) even after unbinding w from cyclic forward, shift+w still causes cyclic forward, ironically the binding causing this problem doesn't have shift+w bound for it, but only w! The problem key that I needed to unbind to resolve this problem was under the Plan Movement menu, Nose Down 'W'. It seems for some reason shift+w is causing this to fire and then make it think it needs to do a cyclic forward when your in a chopper.

To replicate the problem:

1. Use Default Arma 3 controls.
2. Unbind the W key from Cyclic Forward in the Helicopter Movement Keys.
3. Fly a chopper.
4. Press shift+w: causes the chopper to perform Cyclic Forward action.

To see the resolution via unbinding:

1. Unbind W from Nose down in the Plane Movement keys.
2. Fly a chopper.
3. Press shift+w: no longer causes the chopper to perform Cyclic Forward action.

So it looks like something is weird with the W binding for a plane's "Nose down" instruction when holding down the shift key.

*In the above cases where I mentioned shift I always mean Left Shift(haven't tried to see if right does the same).

I don't know if it is related, but generally speaking it seemed to be a issue with vehicles which have two pip systems on the inside, while the PC config is SLI based. I think i still have the issue, will double check when I get home.

BTW this test was done on 560 Ti SLI setup with the newest 337.50 nvidia geforce drivers.

I just did a test on a whole bunch of vehicles.

Right now the following gives me black flicker on mirrors and monitors:
Ifrit HMG/GMG (the one without the gunner seat does not exhibit the issue).
Hunter HMG/GMG (the one without the gunner seat does not exhibit the issue).
Offroad Mirrors/Monitors.
SUV
Submarine
Strider (the one without the gunner seat)

The following gives me a similar to the flicker stutter ghost image on monitors/mirrors:
Hatch Sport
Hatch Normal
Strider (the one with the gunner seat)
Truck

I haven't tested any air related vehicles yet.

It seems whatever is causing this is related to something in the way monitors are done for the gunner/commander/sub driver/gunner specifically, since when those elements are not present the mirrors start working fine, as can be demonstrated with the hunter/ifrit gunnerless vs. gunner present versions, and it seems up to mess up any PiP that are present then including mirrors when it goes wrong.

Guys this issue has been sitting for more than a year now, can we please get some love? :(

I concur, I also have some mirrors etc working now and others not (especially pip in vehicle monitors).

The general comments about running off 1 card instead of two is void now it seems:
for me on two 560 Ti cards this is the difference between 50fps and 29fps, i.e. I get good SLi performance as far as the visual graphics aspect of the game is involved when there isn't a ton of physics all over the place and AI computing pathing. (4.5K view distance 3.5K object distance)

If there is no difference in performance with or without SLI enabled then that is bugged, that's like saying a 580 and a 560 should give you the same performance...

All in all though they need to fix this stuff, essentially the flickering/ghosting problem makes PIP useless which negatively effects gameplay in all the many (and i do mean many) places. I get the affect practicaly everywhere: car mirrors, in car video mirrors, back seat gunner screens, sub screen etc.

Flickering on current Dev build on this date: using 560 Ti SLI.
