I don't know what the fix in the feedback tracker was that is referred to in post #14, so sorry if my solution is already mentioned somewhere else.
I had the same type of problem starting a few days ago and tried all of the suggested solutions but non of them got rid of the problem.
For me the source of the problem was that the continuous zoom in and zoom out controls where bound to the slider on my Saitek X52 throttle control and when the slider is slightly off-center then you will experience what looks like a screen shake but what actually is happening is that your view is constantly zooming in and out by a small amount.
So for people who are still having similar problems then check your keybinds for the "zoom in (continuous)" and "zoom out (continuous)" controls under the View categorie and check if there are any controls bound that could produce such type of behavior (probably only analog controls).
