[vfio-users] Frequent crashing with Overwatch

[Abdulla Bubshait]

I would also like to chime in that this behaviour started popping up for me
too. I am guessing it was introduced in a recent Overwatch update. I used
to play the game fine on my setup until recently. Now, for some reason the
game crashes after a while and I am unsure what could be causing it.
