Manjaro 16.10 Gnome Edition Graphical Interface problem

I just downloaded the latest version of Manjaro 16.10 Community edition Gnome version. I tried to run this distro on my Virtualbox. Basically it went well but I discover some weird problems with the graphical interface. It seems like Gnome did not loaded correctly and left some really annoying artifact. 
I spot some problems on the top panel. Those icons shouldn't be there. I also tried to boot Manjaro 16.10 Gnome on my Laptop using Live USB and still have this problem as well. Is it because the VGA driver or something else, I still try to find out.
