Slight camera vibration with set relative location

Hi there !

I have a really strange bug (?) or maybe I’m missing something…

You can reproduce that in a new third person template. You just have to set the relative location of camera boom like that:

Then, when rotating quickly with pressing and releasing the input, camera vibrates like in that video https://streamable.com/1hnslu (i’m talking about the slight vibration when the pawn is immobile)

Is there something I can do to get rid of that ?
If i am printing the relative location of both camera and camera boom all is equal to 0 when the input is released… Can’t understand what is going on.

Thanks a lot for your help !
