Poor graphics performance on retina display with VirtualBox 4.2.x
|Mac OS X
I'm happily using VirtualBox on a MacBook Pro with Retina display. However, ever since the release of VirtualBox 4.2 moving windows in a guest OS is very slow, i.e. the movement of the window is considerably lagging behind the pointer movement up to a degree where it gets unusable. This happens on both, a Gentoo Linux VM with a XFCE4 desktop and on a Windows Vista VM. The problem also occurs no matter which resolution the MacBook's retina display is configured to use. Moving windows works fine, however, when I move the VM window to a secondary (non-retina) display.
I tried several 4.2.x releases of VirtualBox including 4.2.10 which all showed the same behaviour. I'm currently using 4.1.24 which seems to be the last version not to have this problem.
