11124	4.2.1 and 4.2.2 guest additions 3d support framebuffer issue	hootjr		"There are issues with 3d support (both in OL6 and in Windows7) on 4.2.1 and 4.2.2 r81494.  

4.2.1:
=====
- Linux Guest - If you enable ""Desktop Effects"" from Gnome in OL6, it will work just fine (wobbly windows and all), but the frame buffer is pushing the image up maybe 20-40 pixels.  
- Windows Guest - The same is true in Windows 7 with the WDDM driver-- enable Aero seems to work just fine with effects.  But the image is pushed up 20-40 pixels.
- NOTE: if you go to ""Full Screen"" mode with either Gnome or Windows 7, everything seems to work just fine.  So this only has to do with ""windowed"" mode.

4.2.2:
=====
- Linux Guest - ""Desktop Effects"" don't seem to even allow you to enable them from Gnome anymore with the new guest additions installed.
- Windows Guest - still the pixel issue.
- NOTE: ""Full Screen"" mode still works with Windows7, but does NOT work with Gnome.

I am running OSX Mountain Lion 10.8.2 and Virtualbox 4.2.2 r81494.  "	defect	closed	3D support	VirtualBox 4.2.2	obsolete	3d framebuffer effects		all	Mac OS X
