Seems to be a bug in libunityshell or in some compiz plugin.
Best way to replicate is to install `joystick` and run `ffmvforce test` (or real force feedback device if you have one plugged in), now the desktop crashes. Sometimes other programs (especially if they’re run with Wine) present this behavior. I’ve also tried on liveusb on both Intel and Amd machines with the same result.
