Hello, I have been experiencing ghosting in seamless mode. It works fine in fullscreen and in scale mode. There is also an issue with the guest OS not being properly aligned at the edge between the two monitors (there is an area of overlap). Is this a known bug? If not, what information is useful in debugging this? I run Virtual Box on a Windows 7 box and it doesn't do this. You can see screenshots of my problem here:

3D acceleration or Compiz running on the guest?
If so this is known. Search bugtracker
