Hello,
since the last update (no mods, no developer mode) I have noticed this issue with the trim on the C152.
My trim is assigned to the wheel on the thrustmaster throttle. While I am trying my force feedback yoke, I have notice that the roll was moving when I was trimming (plane stopped on the ground). Looking better, I have noticed this odd behaviour: when I trim, only half of the trim moves, and the roll changes, to then move slowly back to the center.
See these screenshots:
the right trim is always in the same position, while the left trim is moving up and down, when I move the control.
If I look in the cockpit while I’m doing the same operation:
you can see the yoke going from slightly to the right to slightly to the left.
I haven’t check on other planes yet. Am I the only one to have seen this?
In reality, there is a trim tab only on the right-side (passenger side) elevator for the C-152.
Regards

Hmmm… I can’t believe I have never noticed it when I fly on the real thing 
But why the yoke turns?
Yep, the yokes shouldn’t be turning if the only thing you’re inputting is trim, and for sure not on the ground. You might want to check your bindings to make sure there’s not another action being taken when you trim. If there’s no other input being given when you trim, I’d report it.
By the way, the 172 is configured the same way, although on some models, there is a manually adjustable tab on the other side that can be used to adjust minor issues with flight alignment while on the ground (generally not to be done by the average student!!). I think when Cessna moved from the 150 to the 152, they may have added the same “ground adjustable tab” on some models. I haven’t been in a 150/152 in quite a while.

Now, this is where I would like to dig a hole and hide in it 
Indeed, I checked on the C152 and the trim is on one side only. I can’t believe I never noticed it, they make me go around the plane and check it before every lesson 
I did check the bindings, but that control of the thrustmaster is linked only to the trim.
I’ll make further checks next time I run the sim…

I forgot to post these screenshots…
So, there are no binding for the roll axis:
and this is the effect of moving the trim (as well as the trim rotating, of course)
Hmm, here’s a thought… Is the in game yoke turning because the FFB system is turning the physical yoke, or is the physical yoke only reacting to the yoke turning in game? It could be a FFB specific issue because I haven’t ever noticed this. Maybe try disconnecting the yoke and trimming to see if it still happens on the virtual yoke? Either way, you should be able to save your current bindings as a preset and then reset them all to default. Maybe that will help. It’ll rule out a binding issue at the very least.
I did try to disconnect my yoke and leave only the Thrustmaster, it happens the same. Actually, if I move another control binded to the roll (my yoke or the joystick), they go immediately back to the center, so I don’t think MSFS is getting the input from somewhere else.
I don’t really know, now I’m away and I can’t try anything else, but when I’m back I will try to reset bindings to default and see if it happens.
