Sometimes I notice my ZiS-43 vibrating vertically. I don’t know what triggers it, I have noticed at least one instance of it vibrating from spawn. I have seen it stop vibrating too, I again don’t know what the trigger is for that. All instances of the bug have occurred in ground ab. I may have seen this vibration on other Soviet SPAAs (the others I have been used since I’ve noticed the bug are the ZiS-12 and ZSU-37), I’m only certain that it exists for the ZiS-43 though.
I have two clips which both feature the vibration, they’re too large to attach here however.
Youtube is a good place to put videos and link them in here for embedding.
I have the two clips embedded below, I might reply every now and again with future instances, should it be helpful.
Here it can be seen for most of the video, stopping randomly before I fire at the Avenger, and then starting again afterward.
Here it can be seen very briefly twice, once near the beginning of the video and the other time at the beginning of the encounter with the M4A2.
Since posting the above clips, I have played more in the ZiS-43, and am now retiring it for the foreseeable future. I have unfortunately not obtained any clips that might better display the bug. I have, however, made further observation.
A consistent trigger of the vibration is movement. The vehicle tends to begin to vibrate as I begin to accelerate, increasing in amplitude the longer I move for. After stopping, it continues for an amount of time not proportional to the amplitude (as far as I have observed), it does decrease while stationary though. The vibration stops at random.
I said I may have seen this bug on other Soviet SPAAs, I was wrong, I have, since posting the original report, only experienced this bug in the ZiS-43.
Be sure to report this sort of thing on the issue tracker, along with the map and the area/environment you are encountering it.

If you have ULQ enabled and have your graphics down considerably, some objects don’t render.
(Edit - I just tested this myself in test drive.
It only really becomes noticable if you are zoomed in, and Arcade is where it happens, not so much on RB.)
