kernel log

when using hardware accleeration in virtualbox, the gnome 3 desktop and
cinnamon the whole screen moves downward then back to normal constantly for
some reason, this only happens on VirtualBox and not the host, and only happens
with the latest nouveau driver, I'm using NVIDIA Corporation GF114 [GeForce GTX
560 Ti], and XFCE4 on my host

A screenshot of the desktop when it moves downward
