11452	Graphics corruption when using Intel SNA AccelMethod on linux host	JohnAStebbins		"This may be a bug in the the intel xorg driver. I will report a bug with them as well.

Host
Ubuntu 12.10 x86_64 host
xserver-xorg-video-intel 2:2.20

Guest
Ubuntu 12.04 i686

Enable SNA acceleration method in xorg.conf on the host.
Option ""AccelMethod"" ""sna""

The entire screen in the VM will go black as the mouse cursor moves.  Selecting or moving a window will make the window visible again (screen all around the window remains black).

If I change the AccelMethod back to UXA by removing the AccelMethod line from the host xorg.conf file, graphics in the guest work correctly again."	defect	closed	3D support	VirtualBox 4.2.6	obsolete	graphics intel SNA		Linux	Linux
