I had encountered this bug in all three Unity 3D games I tested in Wine so far
- My Summer Car, Escape from Tarkov and Jalopy. I've been always using the
latest Wine version available for my OS (pure Arch Linux), currently using
wine-staging 2.7, and the bug still persist.

Basically, *any* mouse interaction causes the mouse to move what it seems to be
exactly one pixel down and right. When moving the mouse, it makes it harder to
move it up and/or left and easier to move it down and/or right, or like Rencer
explained before, "it looks like something "fighting" with [the] mouse
movement".

HOWEVER, the movement of 1 pixel down AND right also occurs when the mouse
wheel is being scrolled (up or down), or when I click any mouse button (left,
right, middle/scroll click and even thumb 1 and 2 buttons on my mouse).

Since there is a way to play both My Summer Car (
http://steamcommunity.com/app/516750/discussions/2/154644705028276893/ )  and
Jalopy ( http://steamcommunity.com/app/446020/discussions/0/135510669593970925/
) natively by replacing the binaries, I can confirm the issue appears only when
using Wine. It seems that like Rencer said, it affects all the Unity 3D games,
but *only* the one with 3D graphics and only the actual 3D mode, not the menus
(I can confirm that).

I also assumed joystick being an issue. I tried fiddling with regedit to remove
any default joystick binding in My Summer Car, but I didn't found a way to do
so. However, in Jalopy the joystick support is disabled by default, and the
issue still persist.

I also have no other USB devices attached other than my mouse and keyboard. I
didn't test it with PS/2 mouse and keyboard, so I can't say anything about PS/2
devices (I will test it if I found any, but I don't have any near me at the
moment to confirm).

I will attach the bug to My Summer Car and Escape From Tarkov AppDB entries, as
the issues are mentioned both by me and other testers. Jalopy doesn't have
entry yet, so I'll attach it when/if I made one :)

I also suggest Rencer and other finding the bugs to properly tag at least the
Unity 3D games, as we know these are affected :). Someone dedicated enough
could test it with other Unity 3D games (even if they have a native Linux port)
just to make sure, but like I said, I suspect that it's the bug that affects
all the Unity 3D games.
