#877 obsolete 100% CPU load with Windows XP guest and iTunesHelper Nil
Description

Host: Ubuntu Gutsy i386 Guest: Windows XP Professional SP2

After installing iTunes 7.5 from Apple's website I have noticed that VirtualBox uses 100% of the CPU. This is a dual core system (Core Duo T2500 @ 2.0 GHz) so actually only one core at once is at 100%, but I suppose that it would use almost 100% on a single core machine. This obviously makes the machine heat up too. Since I'm new to VirtualBox and I've used it for less than a week, I was unsure about if the VM always used the 100% of the CPU or not, so I first tried to disable tickless (nohz=off) on the host and ACPI on the guest too but that didn't help. Then I noticed that if I logged off the session in the guest CPU usage dropped, so I deduced it should be a Windows process or service what was causing the problem and found it to be iTunesHelper, however in the Windows Task Manager CPU usage for iTunesHelper was around 0-2% as expected so I understand it is a virtual machine issue. After disabling iTunesHelper in the registry so it doesn't load at logon CPU usage was normal again. Then I switched back to ACPI and re-enabled tickless and everything is fine now with iTunesHelper disabled.

#878 fixed compiz + seamless mode : guest/host window layering behaves incorrectly umoeller prurigro
Description

When using 'compiz' and 'virtualbox in seamless mode', the layering of linux windows and the virtualbox layer behave incorrectly. When you click the title bar of a linux window, it moves/remains behind the virtualbox layer. It only works properly when clicking the body of a linux window, where the window moves in front of the virtualbox layer as it should.
