Linux - Black Ops 2 - Weird mouse input

[SpidFightFR]

Hello everyone, i hope you're doing well.

I got this weird issue on Black ops 2 when playing on linux with plutonium. And as far as i can remember it doesn't happen on the base game:
It feels like the mouse is dragging behind, in a kind of mouse accelerated movement, that's not following the movements i input with my real mouse.

I do have one record of said problem but i can't seem to be able to post it...

Do you guys have any idea what it could be, please ?

Best regards
