[Bug 42631] Strange mouse movement in many 3D games, every game that using the Unity-engine is affected with this bug

--- Comment #20 from [e-mail] ---
This bug was initially reported as a normal bug, only affecting game "7 Days to
Die".

Now this bug affects every Unity-enging game, and even some other-engine 3D
games like FalloutNV.https://bugs.winehq.org/show_bug.cgi?id=42872

It is likely this bug also caus Fallout4 camera drift.

"Moving mouse, clicking left or right mouse button, scrolling mouse wheel or
clicking mouse wheel", cause mouse cursor move to bottom right of screen, it
feels like drift or +1px.

Someone think this bug relate to joystick, someone think this is a unfixed
Unity3D "upstream bug". I suspect there is something wrong in mouse signal
handle code. 
Are there something like this?
MOUSEPOS_X = MOUSESIG_X+1;
MOUSEPOS_Y = MOUSESIG_Y+1;

Linux native port of "7 Days to Die" is not affected by this bug. (It suffers
from 3 other bugs: random crash or guaranteed crash or frequently crash)
