I've tried installing Ubuntu Gnome in VirtualBox and VMware Player. In both cases I end up with a weird graphical bug on the desktop. Everything else seems to be working as it should, although VirtualBox crashed after a few minutes when I tried using 2 monitors.
I've also tried installing Ubuntu 13.04 normally, following a guide to installing Gnome 3 then logging on using Gnome 3 instead of Unity. The graphical bug still occurs.
Am I right in assuming that this is a Ubuntu/Gnome 3 issue rather than a VM issue, seeing as this is occurring on two completely separate VM applications? Does anybody know what is happening?
Note: I've installed Ubuntu with Gnome 3 on my laptop, and it works fine. That's why I'm assuming that this issue is somehow VM related, perhaps through "VMware Tools" or "Guest additions".
