I upgraded to Virtualbox 3.0 and then 3.0.2.
I use Vista as a host and Ubuntu as the guest. In Virtualbox 2.0 I was able to run Ubuntu with standard desktop effects. After upgrading I noticed that it can no longer run the standard effects. The effects are slow, menus and windows stay around after you've closed them, menus don't get selected when you mouse over, etc.
I've seen people complain about the performance of 3.0 before but the only solution I've seen is to uninstall 3.0 and use 2.x.
Is that the only option?
