I have tried Ubuntu 11.10, Linux Mint 12, Fedora 15 (I should update to Fedora 16 soon), but I can't help but complain about the performance of this latest distributions virtualized using VirtualBox. Or is VirtualBox that's getting really buggy??? :(
Ubuntu 11.10 feels really slow, clicking on an application using Unity takes forever to bring up the applications main GUI (even gedit is slow). Linux Mint 12 while looks nice but also is problematic. Clicking on Mint Menu shows blank items ... and it only shows up the entries once I wiggle the mouse around. Picture speaks a thousand words, so see below.
Figure 1. Mint Menu shows blank on the left side :(
Another issue I have observed with Linux Mint 12 is that the menu gets out of sync. So like if select Internet it does not move focus to it. But the items to the right gets updated. Again, see below for a screen capture.

Fedora 15 while useful but feels really slow. My host machine is a Core 2 Quad CPU clocking at 2.50 GHz. Yes, the guest is only allocated one core and 1GB of memory, but Linux should not need more than that. Or at least it should be comfortable to use it using that configuration.
Did we succumb to release schedule? Or is GNOME 3 is still in a state of influx? Or VirtualBox is getting really buggy?
