I don't have a solution, but have the same problem. (I don't play games;
happens to me using modeling software.) Been too busy to use it much so
I haven't been looking for a solution, but would love one - it kinda
makes the exercise pointless.

For a while I thought it was Synergy-related[1], but it happens without
running that. System is stock Ubuntu 1604, I'm not passing USB through,
just an Nvidia Quadro K4000. I have a mouse and a trackball, as well as
a mouse-like device for making small, precise motions. When the VM loses
it, they all die.
