16652	Switching to fullscreen crashes X on host	Nick B.		When I try to switch a guest to fullscreen mode (any guest OS) it hangs X on the host for several seconds then eventually completely crashes and restarts. Host OS is Kubuntu 17.04. I'm not sure what logs would be useful but I can provide whatever would be helpful.	defect	closed	other	VirtualBox 5.1.18	fixed			all	Linux
