I have found that with lower resolution than that is configured on my desktop there is mouse issue - mouse is trying to move to one side, even that it is not moving there. But if there is zero motion, it does not move.
But after resolution change all is perfect. Game runs flawlessly on my Debian.
Nothing extracted yet.
Game runs great, but mouse movement frequently gets "trapped" or freezes. Holding left/right trigger down allows movement to always work, but that is not feasible in game or you throw a lot of grenades :)
